Site has broken after changing the php version from 7.4 to 8.1.

Question

My site is perfectly running on php version 7.4. But when I change it to version 8.1 then my site has broken. How to fix?

some error Logs:

Have you get backup before updating the version? you should have to reverse the process first.

Answer 1

You'll have to downgrade to PHP 7.4 or use my Q2A unofficial bugfix branch. It's backwards compatible.

Yes, that right. Version 8.x still bugging
