Updating Themes and Plugins

Updating themes and plugins is a crucial aspect of website maintenance. It ensures that your website remains secure, functional, and compatible with the latest web standards and technologies.

The Importance of Updating

Outdated themes and plugins pose a significant security risk. Hackers exploit vulnerabilities in outdated software to gain access to sensitive information, inject malicious code, or deface your website. In fact, according to a study by Sucuri, 36% of hacked websites in 2018 were running out-of-date WordPress installations. Additionally, outdated plugins and themes may not function correctly, causing issues with the website layout, features, or functionality.

How to Update Themes and Plugins

Updating themes and plugins is a straightforward process. In WordPress, you can check for updates in the "Updates" section of the dashboard. You should regularly check for updates and apply them as soon as possible.

It's also essential to review the changelog or release notes for each update. They provide insight into the changes, bug fixes, and security patches that come with each release.

Updating Best Practices

Here are some best practices to keep in mind as you update your themes and plugins:

  • Backup your website before updating. In case something goes wrong during the update, you can restore your website to the previous version.
  • Test the updates in a staging environment. Before making updates to your live website, create a staging environment. This allows you to preview the changes and test any new functionality or plugins before applying them to the live site.
  • Don't rely on auto-updates. While auto-updates are convenient, they may cause compatibility issues or break your website's functionality. It's best to update manually and review the updates' changelog or release notes.
  • Remove old/unused themes and plugins. Keeping old and unused themes and plugins can pose a security risk, even if they are not active. Remove them from your server to reduce the attack surface of your website.


Updating themes and plugins is crucial for website security, functionality, and compatibility. By following best practices and regularly checking for updates, you can keep your website secure, up-to-date, and functioning correctly.

Incompatible Plugins with Theme

One of the most common issues WordPress users experience is plugin and theme incompatibility. When a plugin is not compatible with a theme, it can cause unexpected issues, which range from minor layout problems to site crashing errors.

According to a recent survey, 87% of WordPress issues reported globally are related to plugins and themes' compatibility. Moreover, 80% of these reported cases are due to incompatible plugins and themes.

Developers create WordPress plugins to enhance a website's functionality, but not all plugins will work with all themes. Incompatible plugins have different programming codes that don't align with the current theme's codes, preventing the theme and plugin from working together. Consequently, a user may experience issues such as layout mishaps, missing widgets, and errors on the site.

One example of incompatible plugins and themes is when a plugin offers customized post types and taxonomies, and the theme's code doesn't match the plugin's setup, which leads to a site malfunction. Another instance is when a SEO plugin updates the site's schema markup, and it's not compatible with the theme, causing layout issues.

It's essential to research plugins before using them and checking if they're compatible with your current theme or not. WordPress plugins and themes alike regularly have compatibility notes published, indicating which plugins work with which themes. A user must conduct their due diligence to avoid plugin and theme incompatibility issues.

If you discover that a plugin and theme don't work together, it's ideal to look for a solution before enabling the plugin. If no fix is available, switch to a more compatible plugin or ask the developer to create a more adaptable plugin.

Lastly, it's crucial to note that when incompatibility issues arise, plugin or theme updates may impact compatibility. Therefore, it's necessary to keep your plugins and themes up-to-date.

In conclusion, being cautious when using WordPress plugins can help avoid incompatibility issues. Checking for compatibility notes before enabling a plugin and updating both plugins and themes regularly can help alleviate the potential for themes and plugins not working together.

Broken layout due to a plugin

One of the most common issues website owners face is a broken layout due to a plugin. This can be frustrating, but it is an issue that can be resolved with a few simple steps.

When a plugin is outdated or incompatible with your website's theme, it can cause layout issues such as overlapping content, broken links, distorted images, or even a complete blank page. This can negatively affect user experience and ultimately lead to a decrease in traffic and revenue.

To resolve this issue, the first step is to identify the problematic plugin. Start by deactivating the most recently installed plugins one-by-one until the issue is resolved. If the problem persists, try deactivating all plugins and activating them one-by-one until the issue appears again. This process helps to identify the specific plugin causing the problem.

Once you have identified the problematic plugin, there are a few potential solutions. The first option is to update the plugin to the latest version, as the update may have resolved the compatibility issue. If this does not work, you can try finding an alternative plugin that serves the same purpose and is compatible with your theme.

In some cases, there may not be an alternative plugin available. In this situation, you can try contacting the developer of the plugin to report the issue and request a solution. Alternatively, you can seek help from WordPress support forums or hire a WordPress developer to resolve the issue for you.

In conclusion, a broken layout due to a plugin can be a frustrating issue for website owners. However, it can be resolved by identifying the problematic plugin, updating or finding an alternative, and seeking support if needed. It is important to address this issue promptly, as it can impact user experience and ultimately damage your website's reputation and revenue.

Security risks with outdated plugins and themes

One of the biggest risks associated with outdated plugins and themes is the potential security vulnerabilities they can create for your website. When themes and plugins are outdated, they often contain known security issues that hackers can easily exploit to gain access to your website. This can lead to data breaches, malware infections, and other dangerous security breaches.

According to a study by Sucuri, outdated WordPress plugins were the leading cause of website hackings in 2018, with over 37% of websites hacked due to outdated plugins. Similarly, WordPress security company Wordfence reported that in 2020, more than 97% of all WordPress vulnerabilities detected were related to plugins and themes.

Outdated plugins and themes pose a significant risk to your website's security, which is why it's important to regularly update them as new versions become available. WordPress provides a simple and effective way to check for available updates and install them directly from the WordPress dashboard.

In addition to regularly updating plugins and themes, it's also important to only install trusted and reputable plugins and themes from reliable sources. Avoid using plugins and themes from unverified sources or unknown developers, as these may contain malware or other security vulnerabilities that can put your website at risk.

To stay ahead of potential security risks, it's important to keep an eye on WordPress security news and updates regularly and take a proactive approach to keeping your website secure. Resources like the WordPress Security blog and the WPScan vulnerability database are great places to start.


Updating your plugins and themes is an easy and important step in keeping your website secure from potential security threats. Keep on top of new updates, install only trusted plugins and themes, and remain vigilant when it comes to WordPress security. With the right precautions and tools, you can ensure that your website remains secure and free from potential security breaches.

Compatibility issues with third-party services/plugins

One of the biggest challenges of running a website with multiple plugins and services is ensuring that all the pieces fit together. Third-party services and plugins can introduce compatibility issues that can cause your website to break or run slowly.

Some common issues that arise when using third-party services and plugins include:

  • Incompatibility with your CMS platform: Not all plugins and services are compatible with all CMS platforms. Before purchasing a plugin or service, make sure that it is designed to work with your platform.

  • Dependency conflicts: Some plugins and services depend on specific libraries or frameworks, which may conflict with other plugins or services that also depend on those same libraries or frameworks.

  • Performance issues: Third-party plugins and services can introduce additional load times and slow down your website. Poorly written plugins can also cause performance issues.

  • Security vulnerabilities: If a third-party service or plugin is poorly written or maintained, it can introduce security vulnerabilities to your site that could be exploited by attackers.

To avoid these issues, it's important to carefully research and test any third-party plugins or services that you plan to use on your website. Here are some tips for ensuring compatibility:

  • Research plugins and services: Before purchasing or installing a plugin or service, research it thoroughly. Check reviews, forums, and other resources to ensure it is compatible with your CMS platform and other plugins you are using.

  • Test thoroughly: Make sure to thoroughly test any new plugins or services you add to your website. Check for any compatibility issues, performance issues, or security vulnerabilities.

  • Keep plugins and themes up to date: Keeping your plugins and themes up to date is crucial for avoiding compatibility issues. Make sure to regularly check for updates and install them as soon as they become available.

  • Consider a staging environment: A staging environment allows you to test new plugins and services in a safe, isolated environment before deploying them to your live website.

By following these tips and being diligent about testing and research, you can avoid many of the compatibility issues that arise when using third-party plugins and services.

Resolving conflicts between plugins

It is common to face conflicts between plugins, especially when using many of them on your website. The conflicts occur when two plugins have the same functionality or manipulate the same component of the website's structure. As a result, the website may become unstable, crash, or break entirely. Resolving such issues is crucial to ensure the website's functionality, speed, and overall user experience.

Identifying conflicting plugins

Before resolving the conflict, you need to identify which plugins are causing the issue. To do this, deactivate all plugins, and then reactivate them one by one, monitoring the website's behavior after each activation. If the website breaks down after activating a particular plugin, that plugin is likely causing the issue.

Resolving Plugin Conflicts

Once you have identified the conflicting plugins, there are several methods you can use to resolve the issue.

  1. Disable or remove one of the conflicting plugins: If the plugins perform the same function, it may be best to remove or disable one of the plugins to avoid conflicts.

  2. Check for plugin updates: Outdated plugins can cause conflicts, so ensure that the conflicting plugins are updated to their most recent versions. The updated versions may contain fixes that resolve the conflict.

  3. Use Compatibility plugins: There are several plugins that provide a compatibility layer between different plugins. One such plugin is the Plugin Organizer that allows you to re-order the plugin execution sequence or selectively disable some plugins on specific pages.

  4. Reach out to plugin support: Some plugin developers provide support that can help in resolving conflicts. Plugin developers may have different ways of resolving conflicts, making it important to communicate with them.

  5. Debugging: This involves investigating the code or identifying the conflict from the source. It is often a technical process that requires expertise, making it essential to consult with a professional developer.


Plugin conflicts can significantly impact website functionality and user experience. Hence, identifying and resolving plugin conflicts is crucial to website stability. To avoid conflicts, ensure your website uses only the necessary plugins, keep them updated, and monitor your website periodically. In case of conflicts, try the various methods mentioned above to restore your website's functionality. Remember, the ultimate solution depends on each plugin's unique functionality and coding, so some conflicts may require expert debugging assistance.

Debugging compatibility errors

Sometimes, despite having updated all themes and plugins, and ensuring that everything is compatible with your website, compatibility problems can still occur. When a plugin or theme isn't compatible with your website, it can lead to errors and issues that can be frustrating to solve. In this section, we will discuss how to debug compatibility errors.

One way to debug compatibility errors is to use a tool called the Plugin Conflict Detector. This tool is a plugin that checks for conflicts between two or more plugins by disabling all plugins except two at a time, and then testing each one individually. This will help you to identify which two or more plugins are conflicting and causing the issues.

Another way to debug compatibility errors is to use debugging tools like Chrome DevTools. Chrome DevTools is a set of web developer tools that can help you debug and troubleshoot compatibility issues. You can use the Console panel in Chrome DevTools to debug issues with scripts, and use the Network panel to track down issues with resources not loading correctly.

If you are still unable to resolve compatibility issues, you can try disabling all plugins and themes except the one you are trying to troubleshoot. This will help you identify the source of the problem.

It is also important to keep in mind that updating a plugin or theme can sometimes cause compatibility issues with other plugins. In such a case, it may require contacting the plugin or theme developer, or rolling back to a previous version of the plugin or theme.

Debugging compatibility errors can be tricky, but with the right tools and methods it can be much easier and less time-consuming. Remember to always keep your plugins, themes, and website up-to-date to avoid any compatibility errors. If you need further assistance, there are plenty of online resources like Stack Exchange or the WordPress support forums where you can ask for help from a community of experienced developers.

Useful resources:

  1. Plugin Conflict Detector
  2. Chrome DevTools Documentation
  3. Stack Exchange WordPress Development

In conclusion, theme and plugin compatibility is a crucial aspect of maintaining a website. Updating themes and plugins is essential to ensure that they do not become incompatible with each other and cause issues in the future. Similarly, understanding which plugins may be incompatible with your chosen theme can save a lot of headaches later on. Broken layouts caused by plugins can also be frustrating, but identifying them can be done by simply deactivating all plugins and then reactivating them one by one until the culprit is found.

Outdated plugins and themes present significant security risks, so it is essential to update them regularly and remove any that are no longer in use. Compatibility issues with third-party plugins and services will crop up from time to time, but researching plugins before installing them and seeking support can help minimize them.

Resolving conflicts between plugins may require some technical knowledge, but deactivating conflicting plugins and consulting support articles are good starting points. Finally, debugging compatibility errors may seem daunting, but it can be done with patience and a systematic approach.

In summary, maintaining theme and plugin compatibility may seem like a tiresome task, but it is essential to ensure your website is running as efficiently and safely as possible. Regularly updating, researching, and troubleshooting compatibility issues are all necessary steps to take. By doing so, website owners can avoid frustrating issues, boost their website's functionality, and protect their website against possible security threats. It is always wise to keep one's website as secure and efficient as possible, so don't forget to prioritize theme and plugin compatibility in your website maintenance plan.
