Causes of WordPress Plugin Errors

Some of the main causes of WordPress plugin errors are as follows:

  • Poor Coding: You may have installed a poorly coded plugin.
  • Conflict with Theme: Your site’s theme may develop a conflict with a plugin due to any number of reasons.
  • It Might Conflict with other Plugin: When plugins offering similar functionality are installed, there can be a conflict.
  • Conflict with WP: Sometimes the code of a plugin may not be compatible with the code of the WP core files.

Fixing Plugin Errors:

So there are many reasons why you could be seeing the WordPress plugin error message. When it comes to fixing the problem, you will have to take steps based on what kind of message appears on the screen.

1. A Visible Plugin Error Message:

If you can view the plugin error message, you can find the location of the file the error is associated with. This makes it easier for you to identify the plugin that has been causing this error. The message has an error code that simplifies the troubleshooting process.


The error message usually contains the following error code:


Here the ‘pluginfolder’ and ‘pluginname’ are variables depending on the name of the plugin that has been causing the error. Once the problematic plugin has been identified, you can easily deactivate it. It is also recommended to reach out to the plugin developer to inform them about the issue so that they can fix the plugin.

2. White Screen appears in Admin Area:

Sometimes the WordPress plugin error is accompanied by the white screen error in the admin area. This means that it will not be possible to deactivate the plugins using the admin area. In that case, you should use the following steps for deactivating all the plugins:

  • Use an FTP for connecting to your WP site
  • Take a backup of all your plugin files and folders. These folders are located at
  • Delete the plugins and folders present in the plugin folder
  • Then upload the plugins one by one to one to identify which plugin has been causing the error


It is worth knowing that when you delete the plugins, they are all automatically deactivated. But uploading them back to the folder again doesn’t just reactivate them at once. You will have to reactivate one plugin at a time. This is a simple process but it will be required to test each plugin.

3. Access to Plugin Admin Area:

If the error message doesn’t contain information about the error-prone plugin, it can be a little difficult to identify the plugin. In this scenario, it is assumed that you have access to the plugin admin area.

In this case, you should follow these steps to fix the WordPress plugin error:

  • Deactivate all the plugins installed on your site
  • Open
  • Deactivate all the plugins using the steps mentioned in the second point above
  • Reactivate the plugins, one at a time
  • Every time a plugin is reactivated, check the website to find if the error message appears

Even when this method takes some time to test all the plugins, it is an effective and simple strategy to find out which plugin has been causing the error message in WordPress. In rare cases, it is not the plugin that may be causing the plugin error message. This can be confirmed if you notice the message even when all the plugins have been deactivated using the above-mentioned steps.

4. If Plugin is Not the Cause:

So if you deactivated all the plugins and are unable to get rid of the plugin error message, you will have to identify the source of the problem. It may be caused due to an error in the theme or due to a conflict with a theme. There is a growing trend for having additional features and functions in theme designs, especially to fight off the competition. This can, however, increase the risk of conflicts between themes and plugins. The risks are even higher when there are plugins on your WP site that have functions similar to the theme.

Many developers now copy the code from plugin codes. So when you install such plugins, you are highly likely to come across error messages. There are many other causes of plugin errors in WordPress.

Additional Causes:
A plugin error message may be caused due to corrupt core WordPress files. So one way to fix the problem, if other methods are not working, is to re-load all the core WP files. In fact, if you continue to find the error and cannot find a solution, you may consider installing WordPress again. The 000Webhost blog has an elaborate post on how to install WP. It explains the process in a simple and easy to follow manner.

The WordPress plugin error message may also be caused due to corrupt .htaccess file. In this case, you will have to delete the file through an FTP and load a previous version from backup. It is very rare, but the error may also be caused due to resource limitation. This happens when a plugin is a resource hungry. It can result in the white screen error when the memory and CPU limits have been exhausted.


So there is no one certain reason why you could be facing the WordPress plugin error. You will have to go through all the above-mentioned steps to ensure that the root cause is addressed and fixed. If you are unable to find the cause, it may be required to reinstall WordPress itself – a topic on which you can find all the guidance in the 000Webhost blog post. Make sure that you take a backup of your WP files and database before taking this step.
