I logged in as Administrator and enabled Maintenance Mode. After logging off, I can not login anymore.
I tried to cancel the Maintenance mode using $CFG->maintenance_enabled=0; in the config file. I can now see my website, but I can still not login. When I try to login the website is trying to redirect me (but I dont have any redirects setup)
When I put my username and password for the admin - it says file not found and also my URL now has https: at the begining, which it didnt use to have.
