Hi,
I have been developing things here with php8 for quite a few months now and any issues I have come across have been fixed.
However, I am of course not able to test things with all combinations of wppizza and all other wordpress plugins and/or themes so there is naturally always a possibility that in certain settings some issues may arise.
So, in essence, as far as I am aware it works just fine with php8 , but if there should be any issues I am not aware of I will of course address those asap .
It’s usually just a matter of hours from being told about it until an update of the plugin is made available if the precise error/issue can be pinpointed from the debug.log (provided it is indeed an issue with wppizza and not some other plugin/theme)
To do that, debug must be enabled of course – see : https://docs.wp-pizza.com/troubleshooting/
hope that helps
