Common Causes of WordPress Install Error 500

Plugin Conflict

One common cause of WordPress install error 500 is a conflict with a plugin. This occurs when two or more plugins have incompatible code that clashes and causes the server to throw an error. To identify which plugin is causing the conflict, you can disable all plugins temporarily and then reactivate them one by one until the error occurs again. This process of elimination will help you pinpoint the specific plugin that is causing the issue.

Theme Conflict

Another potential cause of the WordPress install error 500 is a conflict with the theme you are using. Similar to plugin conflicts, certain themes may have incompatible code that leads to the server error. To test if the theme is the culprit, you can switch to a default WordPress theme such as Twenty Twenty-One. If the error disappears, then you know that the issue lies with your previous theme.

Corrupted .htaccess File

One of the most common causes of a WordPress install error 500 is a corrupted .htaccess file. The .htaccess file is a configuration file that tells the server how to handle certain requests. If this file becomes corrupted, it can result in a server error. To fix this issue, you can try regenerating the .htaccess file by renaming the current one and then navigating to Settings > Permalinks in your WordPress dashboard. Click on the “Save Changes” button, which will regenerate a new .htaccess file with the correct configuration.

PHP Memory Limit

WordPress websites rely on PHP to function, and if the PHP memory limit is too low, it can lead to an error 500. This usually occurs when your website has a large number of plugins or complex themes that require more memory to execute. To increase the PHP memory limit, you can edit the php.ini file or add a code snippet to your wp-config.php file. Alternatively, you can contact your hosting provider and ask them to increase the PHP memory limit for you.

Folder and File Permissions

Incorrect folder and file permissions can also trigger a WordPress install error 500. The server needs appropriate permissions to read and execute files, and if these permissions are set incorrectly, it can result in a server error. To ensure the correct permissions are set, you can use an FTP client to modify the file permissions of your WordPress files and folders. The recommended permissions for folders are 755, and for files, it is 644.

Plugin Compatibility Issue

Sometimes, a WordPress install error 500 can occur due to a compatibility issue between a plugin and a specific version of WordPress. If you have recently updated WordPress or a plugin, it’s possible that the updated version is not compatible with your other installed plugins or with your current WordPress version. In this case, you can try deactivating the recently updated plugins to see if the error resolves. If it does, you can reach out to the plugin developer for assistance or consider finding an alternative plugin that is compatible with your setup.

Insufficient Server Resources

When your website doesn’t have enough server resources, such as CPU or memory, it can result in a WordPress install error 500. This is particularly common on shared hosting plans where multiple websites are hosted on the same server. If your website receives a sudden surge of traffic or if there are other resource-intensive processes running on the server, it can lead to a server error. To resolve this issue, you can consider upgrading your hosting plan to one with higher resources or optimizing your website to reduce the strain on the server.

Conflicting Server Settings

In some cases, conflicting server settings may be the cause of the WordPress install error 500. These conflicting settings can include conflicting PHP configurations, security modules, or server software conflicts. To troubleshoot this issue, you may need to consult with your hosting provider or server administrator to ensure that the server settings are compatible with your WordPress installation.

Corrupted Core Files

If the core files of your WordPress installation become corrupted, it can result in an error 500. This can happen due to incomplete or failed WordPress updates, unauthorized changes to core files, or malware infections. To repair corrupted core files, you can try using the WordPress built-in repair functionality. This can be accessed by adding the following line of code to your wp-config.php file:

define( 'WP_REPAIRING', true ); 

After adding this line, you can access the repair functionality by visiting the following URL: yourdomain.com/wp-admin/maint/repair.php. Follow the on-screen instructions to repair your WordPress core files.

Faulty WordPress Update

Occasionally, a faulty WordPress update can cause a WordPress install error 500. This can happen if the update process is interrupted, if incompatible plugins or themes are present, or if the update encounters other errors. To resolve this issue, you can try reinstalling the latest version of WordPress. Before doing so, it is recommended to backup your website to ensure that your data is safe. Once the backup is complete, you can follow the detailed steps outlined below to reinstall WordPress.
