Hi everyone, so this is my first-time using grav, I know there is a lot to read. I am working on my Fedora 33 workstation. I have PHP 7.4.12 installed and can run the webserver. When I run this in the webroot though I get a unch of issues:
[::1]:54302 [500]: GET / - Uncaught Error: Interface 'JsonSerializable' not found in /home/blupace/hugo/Grav/system/src/Grav/Common/Data/Data.php:19
