Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
Could you also provide the URL of that page, which is showing the Page not found title? You can provide it in the designated Sensitive Data section for us to investigate.

It is completely secure, and only our support staff has access to that section.
You can also check this link on how to add your page’s title:

I hope that helps. Thank you, and looking forward to your update.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
Thank you for providing more details.
1. Can you please attempt to clear your website cache and see if your page title shows the correct value?
2. Also, this might be a Buddypress related issue. Please head over to WordPress Dashboard > Rank Math > Titles & Meta > *bp related CPTs*
Then, hit the save button once.
3. Lastly, if the issue is still there after following 1. and 2., please conduct a plugin/theme conflict test by following this detailed guide: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
Let me know how it goes.
We are looking forward to helping you.
