Thanks for the report.

WordPress 5.8.x doesn’t yet support PHP 8.x. In testing with 5.9-RC4 there are still a lot of warnings so hopefully there’ll be an RC5. Overall I’m surprised you got as far as the plugin page…

Once WordPress 5.9 is released I’ll be releasing WPf2b 4.4. That’s been tested on PHP 8.1 and will require a minimum version of 7.4 (I’ll put together some pre-release notes later).
