Conflict between RankMath Pro and Elementor causing HTPP 500 errors

Hello,

We apologize for the issue you are facing with the HTTP 500 errors when using Rank Math SEO Pro alongside Elementor. This type of error can often be caused by conflicts between plugins or themes, and it seems you’ve already identified that disabling Rank Math resolves the issue.

Here are a few steps you can take to troubleshoot and potentially resolve this conflict:

1. Check for Plugin Conflicts: Temporarily disable all other plugins except for Rank Math and Elementor to see if the issue persists. If the error goes away, re-enable the plugins one by one to identify which one is causing the conflict.

2. Increase PHP Memory Limit: Although you mentioned having 2 GB of RAM allocated, ensure that your PHP memory limit is set appropriately in your wp-config.php file:

   define('WP_MEMORY_LIMIT', '256M');

   You can adjust this value as needed.

3. Enable Debugging: Enable WordPress debugging to get more information about the error. You can do this by adding the following lines to your wp-config.php file:

   define('WP_DEBUG', true);
   define('WP_DEBUG_LOG', true);
   define('WP_DEBUG_DISPLAY', false);

   This will log errors to a debug.log file in the wp-content directory, which may provide more insight into what is causing the HTTP 500 error.

4. Check Server Error Logs: Review your server’s error logs for any specific messages related to the HTTP 500 errors when Rank Math is enabled. This can often provide clues about what is going wrong.

5. Update Everything: Ensure that all your plugins, themes, and WordPress itself are updated to their latest versions, as updates often include bug fixes and compatibility improvements.

6. Contact Hosting Provider: Sometimes, server configurations or restrictions can cause issues. It might be worth reaching out to your hosting provider to see if they can identify any server-side issues that could be contributing to the problem.

If these steps do not resolve the issue, please reply to this ticket with any error messages you find in the debug log or server logs, and a human agent from our support team will assist you further.

Thank you for bringing this concern to our attention, and we hope to help you resolve it soon!
