Testing php requirements

There is a php file to test all the requirementes for the Grav cms?

is there*
We have an issue updating the admin and plugins, it looks like the update have been done but after a page refresh the update is still avaible.

The “Problems” plugin should do that on the first page load. You can run it again by removing the cache/problem-check-* file.

From which version of Grav/Admin are you upgrading?
