I removed it after enabling redirection. However, redirection still works.

Hello,

I apologize for the issue you are facing with the redirection still occurring even after removing it from the plugin. Here are a few steps you can take to troubleshoot this issue:

1. Check for Other Redirection Plugins

Make sure there are no other redirection plugins installed on your site that might be causing the redirects. If you find any, please deactivate or remove them.

2. Check .htaccess File

You should also check your .htaccess file for any lingering redirection rules. You can do this through the Rank Math plugin by navigating to WordPress Dashboard → Rank Math SEO → General Settings → Edit .htaccess. If you see any additional redirection rules, delete them and save the changes.

3. Theme or Plugin Conflict

Sometimes, conflicts with other plugins or themes can cause unexpected redirects. You might want to perform a quick conflict check by enabling Troubleshooting mode and disabling Rank Math temporarily to see if the issue persists. If it stops, then re-enable Rank Math and check other plugins one by one.

4. Clear Cache

If you are using any caching plugins, make sure to clear your cache after making changes to ensure that old redirects are not being served from the cache.

If you’ve tried these steps and the issue still persists, 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!

Random URLs Redirecting Even When No Redirect Was Created » Rank Math

Hello,

The URLs you shared are for your authors, and they are redirecting to your homepage.

This usually happens when the Author archives option is disabled in Rank Math > Titles & Meta > Authors

Once you enable the option, those URLs should be working fine.

Looking forward to helping you.
