Overview

Some users hosting WordPress sites on Hostinger have encountered a 500 Internal Server Error when attempting to sync articles from Content Genius to their WordPress site using the Search Atlas plugin. This error is typically related to a backend conflict between the Search Atlas plugin and the Hostinger hosting environment.

Steps to Resolve the 500 Error

Try the following steps in order to resolve the issue on your own before contacting support:

  1. Update the Search Atlas plugin. Make sure you are running the latest version of the Search Atlas WordPress plugin. Go to your WordPress admin dashboard, navigate to Plugins > Installed Plugins, and update Search Atlas if an update is available.
  2. Deactivate and reactivate the plugin. In Plugins > Installed Plugins, deactivate the Search Atlas plugin, then reactivate it. This can clear authentication or connection state issues that cause 500 errors.
  3. Re-enter your API credentials. After reactivating, go to the Search Atlas plugin settings and re-save your API key or authentication credentials to re-establish the connection between Content Genius and your WordPress site.
  4. Check for plugin conflicts. Temporarily deactivate all other plugins, then attempt the sync again. If the sync succeeds, reactivate your other plugins one at a time to identify the conflicting plugin.
  5. Increase PHP memory limit. Hostinger environments sometimes have low PHP memory limits that can trigger 500 errors. In your Hostinger control panel or via your wp-config.php file, try increasing the PHP memory limit (for example, add define('WP_MEMORY_LIMIT', '256M'); to wp-config.php).
  6. Retry the sync. Once you have completed the steps above, return to Content Genius and attempt to sync the article again.
