Could someone please try to explain, why suddenly one has to log in to subscribe to my feed?
It doesn't matter if you log in as a subscriber or an administrator as long as you just am logged in.
I've tried to change to Ten Twenty and to disable all and every plugin, but the problem doesn't vanish for those reasons.
It seems that some file has been password protected - I just don't know wish one and where to look. And I do not know, of course, how this has happened :(
Could someone please help?
