404 error in sitemap

Hello,

We apologize for the issue you are facing with the 404 error on your Rank Math sitemap. It sounds frustrating to have to flush permalinks every day. Here are some steps you can take to help resolve this issue:

1. Flush Permalinks: You can flush permalinks by navigating to your WordPress admin area and going to Settings → Permalinks. Simply click the Save Changes button, even if you don’t make any changes. This should help fix the 404 error temporarily.
   

2. Exclude Sitemap from Caching: Ensure that your caching plugin is properly configured to exclude the sitemap from being cached. You can refer to this dedicated knowledgebase article for guidance on how to do this.

3. Disable Transient Caching: If the problem persists, you might want to disable transient caching for your sitemap. You can add the following filter to your theme’s rank-math.php file:

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

4. Check for Plugin Conflicts: Sometimes, other plugins can interfere with the sitemap functionality. You can use the Health Check plugin to check for any conflicts.

5. Check Robots.txt: Ensure that your robots.txt file is not blocking access to your sitemap. You can check this in Rank Math SEO → General Settings → robots.txt.

If you continue to experience issues, please reply to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for raising this concern!
