WordPress is one of the most popular Content Management Systems (CMS) used for creating websites. It is easy to use, flexible, and offers a wide range of functionalities. However, despite its popularity and user-friendliness, WordPress can still throw some errors that can be frustrating for users. In this article, we will discuss the 50 most common WordPress errors and how to fix them.
1. How to fix internal server error
Internal server error is a generic error that can occur on WordPress due to various reasons. It can be caused by a corrupted .htaccess file, plugin conflict, PHP memory limit, or a server issue. Here are some steps you can take to fix internal server error on WordPress:
Check the .htaccess file: A corrupted .htaccess file can cause internal server error on WordPress. You can try renaming the .htaccess file in your WordPress root directory to something else, like .htaccess_old, to see if the error goes away. If it does, then you can generate a new .htaccess file by going to Settings > Permalinks and clicking “Save Changes” without changing anything.
Increase PHP memory limit: A memory limit issue can also cause internal server error on WordPress. You can try increasing the PHP memory limit by adding the following code to your wp-config.php file:
define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
This will increase the PHP memory limit to 256MB. You can adjust this value according to your needs.Deactivate plugins: A plugin conflict can cause internal server error on WordPress. You can try deactivating all plugins by renaming the plugins folder in your WordPress installation directory. To do this, connect to your website via FTP or File Manager and navigate to wp-content. Rename the plugins folder to something like plugins_old. Then, try accessing your website again. If the error goes away, then you can reactivate the plugins one by one to see which one is causing the error.
Check server logs: If the above steps do not fix the internal server error, then it could be a server issue. You can check the server logs to see if there are any errors or issues that could be causing the error. Contact your hosting provider for assistance in checking the server logs.
In conclusion, internal server error on WordPress can be caused by various reasons. By following the above steps, you can fix the error and get your website back up and running.
