Hello. At a local php 7 server, and the homepage is full of green checkmarks (no errors; i believe this is the doing of problems plugin) but the contents still wont load.
i do have in the same server, a drupal 8 working, so i guess it wont be a server problem
BTW problems plugin has been updated to address an issue where ZIP extension was found missing but incorrectly reported as working. This is why flaviocopes asked you about that particular extension.
