CodeIgniter 4 Playground

This is a known issue with the app/ folder being from an older version. I have a pull request to fix it (https://github.com/codeigniter4projects/...und/pull/8), I will see if I can get that in.

Just to warn you, Playground won't necessarily work with a modified version of system. That's a great way to "play" with the framework but you will likely need to make changes to the app itself as well.

@John_Betong Okay that is merged, try pulling the latest version of Playground and see if you have better luck.
