I changed the php version from 7.0 to 8.0 on my cloned site, then hit the reboot button. The only thing that happened was taking my site offline with the message: “There has been a critical error on this website. Please check your site admin email inbox for instructions.”
Do I need to wait for the reboot to work? Or is this an error you need to address? Site no longer available.July 21, 2021 at 7:59 pm #1182474Patrice WilliamsParticipantThis reply has been marked as moderator-only.July 21, 2021 at 9:05 pm #1182535udadminKeymaster
There is no need to reboot after changing PHP version; the PHP engine restarts itself and there’s no benefit to restarting everything else via rebooting.
If you are seeing that message, then WordPress is telling you that there was a PHP error. So very likely one of your components is not PHP 8 compatible, and you’ll need to switch back to PHP 7.X and upgrade it.

Thanks. I did downgrade and did not hit reboot and that did the trick.July 22, 2021 at 9:57 am #1183088Bryle CroduaModerator
