Solved it.
Did a nano /vendor/illuminate/support/Manager.php
Found line
public function driver($driver = null)
Changed null to 'smtp' and saved. Now the page works properly.
I headed into settings, typed smtp back into the box in mail config and saved. Then I went back to the same file and changed it back to null. Now it works.
Now I just have to get my smtp on the server to work. Which it doesn't for some reason..
