Updating from 1.15.1 to 1.16.4: no login possible
Fragment of a discussion from Project:Support desk
You need to point $wgServer to the new URL.
Yes, I tried that. But setting wgServer somehow doen not change anything.
But, that is only a side issue. The mein issue is indeed, that the login URL does not do anything (as the other...).

Huuh, just visited your site. You're not actually redirecting from taunusklub-niederreifenberg.de to taunusklub.schmidt-schmitten.com, you're displaying it in a frame, which is the cause of your problems. Use HTTP redirects.
