Hello, I’m sorry to hear that you’re experiencing issues with redirections on your site. It seems that you’ve made changes to the permalinks on your site and are facing difficulties with the redirections.
Based on the information you’ve provided, it appears that you’ve already tried to manually add 301 redirections to the URLs, but they are still not redirecting to the correct URL and are instead going to the homepage.
To address this issue, I recommend checking the redirections set up in Rank Math. You can use the Redirection Debugger to diagnose the issue further and ensure that there are no conflicting or incorrect redirections set up.
If you’re using Rank Math, you can also utilize the Auto Post Redirect feature to automatically redirect posts, pages, taxonomies, and CPTs. This feature ensures that any attempts to locate an old URL are redirected to the new address.
If you’re still facing issues after checking the redirections and using the Redirection Debugger, please feel free to reply here, and a human agent from our support team will assist you further.

I hope this helps!
