Hello,
I apologize for the issue you are facing with the Rank Math SEO plugin causing a 500 HTTP error on your page sitemap. This type of error can often be related to server issues or conflicts with other plugins or themes.
Since you’ve already used the Health Check plugin to troubleshoot, here are a few additional steps you can take:
-
Check for Plugin Conflicts: Ensure that all other plugins are deactivated except for Rank Math. If the error resolves, reactivate each plugin one by one to identify the conflicting plugin.
-
Theme Conflict: Switch to a default WordPress theme (like Twenty Twenty-One) to see if the issue persists. If it resolves, the problem may lie within your theme.
-
Server Error Logs: Check your server error logs for more specific information about what might be causing the 500 error. This can provide insights into whether it’s a memory limit issue or something else.
-
Increase PHP Memory Limit: Sometimes, increasing the PHP memory limit can resolve such issues. You can do this by adding the following line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
-
Reinstall Rank Math: If none of the above steps work, consider reinstalling the Rank Math plugin to ensure that all files are intact and not corrupted.
If you continue to experience issues after trying these steps, please reply to this ticket with any error messages you find in your server logs, and a human agent from our support team will assist you further. Thank you for your patience!

I have disabled all plugins and activated the default wordpress theme and checked for page-sitemap. It worked but then i enabled rank math seo plugin after which the page-sitemap is not loading. so the issue is with rank math. I have also changed the php memory limit to 256M and tried it, then 512M also but none worked.
