Those methods should already have the \ReturnTypeWillChange attribute set as of XF 2.2.8.

Are these errors persistent or could they have occurred as one-offs during/preceding the upgrade?

 

[ZixDev]

I upgraded to XF 2.2.8 when using PHP 8.0.13, there were no errors.
After that, I upgraded PHP to 8.1.0, then go to forum index and get its errors.

If you're able to access the file health check it might be worth verifying all files have the expected contents. Or, failing that, re-download XF and overwrite the files.

Thank you, I will try that.

Update: I've re-download XF and overwritten the files, and it working.
It is my fault: I'm not updated to 2.2.8 when using PHP 8.0.13
