Just upgraded to 1.7 RC4 from 1.6ST. Since then, I am no longer able to log in to the SCP page. I enter my credentials, and it redirects to the wrong address.
http://blahblahbla.com/scp/scp/index.php?(http://blahblahbla.com/scp/scp/index.php?)
If I remove the extra /scp it takes me right back to the login screen, and here we have a vicious cycle.
I have no idea where to start looking at this point, there we no errors in the upgrade, everything went just like it was said it should. I was able to navigate through the staff and admin pages immediately following the upgrade, but now can't even get logged in.
Any help on this would be greatly appreciated!
Also, there are no mod-rewrites or anything in place. This is on a Server 2012 server with IIS8 if that helps.
