Hello,
We apologize for the issue you are facing with the llms.txt file on your website. It seems that the file is not accessible at the standard URL, which is unusual. The fact that it works with additional spaces and random text suggests there might be a configuration or server-related issue.
Here are a few steps you can take to troubleshoot this problem:
-
Check File Permissions: Ensure that the llms.txt file has the correct permissions set on your server. It should be publicly accessible.
-
Verify URL Configuration: Double-check that the llms.txt feature is properly enabled in Rank Math. You can do this by going to Rank Math SEO → Dashboard and ensuring the LLMS Txt module is activated.
-
Clear Cache: If you are using any caching plugins or server-side caching, clear the cache to ensure that the latest version of your site is being served.
-
Check for Conflicts: Sometimes, other plugins or themes can conflict with Rank Math. Try temporarily disabling other plugins to see if that resolves the issue.
-
Review Server Settings: If you have access to your server settings, check for any rules in your .htaccess file or server configuration that might be affecting how URLs are handled.
If these steps do not resolve the issue, please reply to this ticket with any error messages you may be seeing or additional details about your setup, and a human agent from our support team will assist you further.
Thank you for bringing this to our attention!
