Page Sitemap Not Working

Hello,

We apologize for the issue you are facing with the page sitemap. The error message you are encountering, "There has been a critical error on this website," typically indicates a conflict with another plugin or theme.

Here are some steps you can take to troubleshoot and potentially resolve the issue:

1. Check for Plugin Conflicts: Use the Health Check plugin to identify if there is a conflict with another plugin.

2. Clear Cache: If you are using any caching plugins, make sure to clear the cache after making changes.

3. Check for Static Files: Ensure that there are no static files with the same name as your sitemap file (_sitemapindex.xml) in your server. You can check this via FTP.

4. Add Filter to Theme’s rank-math.php File: If the above solutions don’t work, you can add a filter to your theme’s rank-math.php file. Here’s how:

   • Navigate to WordPress Dashboard → Tools → Theme File Editor (Block Editor) or WordPress Dashboard → Appearance → Theme File Editor (Classic Editor).
   • Choose the rank-math.php file from the right sidebar and add the following filter:

     add_filter( 'rank_math/sitemap/enable_caching', '__return_false');

   • Click on the Update button to save your changes.

5. Validate Your Sitemap: After making these changes, validate your sitemap using the Validate XML Sitemap tool to ensure it is correctly configured.

If you continue to experience issues after trying these steps, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.

Thank you for raising this concern!
