Hi All,
I myself like many was having this admin login problem. It would just seem to get stuck in a loop so I spent the past 2 hours debugging going through the code and I tracked it down to a problem (although not sure why) with line 41 in scp/login.php
I commented out the header redirect
//@header("Location: $dest");
and it now works perfectly fine.
Just thought I would post here and would ask if anyone else is having the same issues to try this fix and reply back to see if it worked for you.
Cheers!
