PHP serve error

Hello Team, I'm Cheri, JR PHP developer, and am working on a PHP project using the new version of codeigniter4. I'm facing some issues on my Cv Writing Service UK website on the page of Signup. However am having an issue with the PHP on OpenSUSE tumbleweed, has anyone attempted a comparable task using OpenSUSE?

I tried several recommendations from stack overflow but none got it working,
