Strange admin redirect ??

Hi,

I have a weird problem.
I'm running edu-clean theme and yesterday, everything worked just fine.
But now, when I try to login as admin, it redirects to this (instead to admin login):
"http://my_domain.com/wp-login.php?redirect_to=http%3A%2F%2Ftreport.si%2Fwp-admin%2Findex.php"

Help,pls!
