404 Page not found

Hello,

We apologize for the issue you are facing with your sitemap. It seems like you might be encountering a problem that could be related to several factors. Here are some steps you can take to troubleshoot the 404 error:

1. Check Sitemap URL: Ensure that you are using the correct sitemap URL, which should typically be https://yourdomainname.com/sitemap_index.xml.

2. Validate Your Sitemap: You can validate your sitemap using the Validate XML Sitemap tool to check if there are any issues with its configuration.
   

3. Ensure Posts Are Set to Index: If all your posts are set to noindex, your sitemap may appear empty. Go to Rank Math SEO → Titles & Meta and ensure that the Index checkbox is enabled for your posts.
   

4. Check for Plugin Conflicts: Sometimes, other plugins can conflict with Rank Math. You can use the Health Check plugin to identify any conflicts.

5. Flush Cache: If you are using a caching plugin, try flushing the cache and excluding the sitemap from caching.

If these steps do not resolve the issue, 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!

Hello,

In this case, please add this rewrite code to your NGINX config file (if not yet):

# START Nginx Rewrites for Rank Math Sitemaps
rewrite ^/sitemap_index.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
rewrite ^/([a-z]+)?-sitemap\.xsl$ /index.php?xsl=$1 last;
# END Nginx Rewrites for Rank Math Sitemaps

If you’re unsure about adding these rules, please contact your server administrator or hosting support, who can help you out.
