Hi,
I have recently made an upgrade to my Expression Engine install, and now for some reason I seem to be unable to log into the admin control panel. It is a similar situation as was listed back here http://ellislab.com/forums/viewthread/175297/
When I login with an authenticated account, I am redirected to c=homepage but then immediately redirected back to the main login page. Session data for the log in user is stored in the database, so the login procedure seems to be working - however S is always set to 0 in the browser URL bar. I have tried setting it manually from the value in the database, but even then I get redirected back to the login page.
Even if I try to log in with bad data, normally it would come up with a flash message saying ‘Bad Login’ however that doesn’t even show, I just don’t get sent through to the c=homepage section, just instantly redirected to the login section with no notification.
I’ve tried setting the $config[‘admin_session_type’] and $config[‘cookie_domain’] which did nothing, and I have checked the paths in the config file which all seem to be correct, so I’m at a bit of loss right now!
