Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
This is a known issue with the CMB2 library and PHP8 and it’s already been fixed on their repository: https://github.com/CMB2/CMB2/pull/1417
However, this fix has not made it through the release version of that library and that’s why we haven’t still updated the library to have this fix added as well.
When they release this into production we’ll update the library and the issue would be fixed.
I hope that helps.
Thank you.
