Yesterday after restarting our Zend Server, I am unable to log in to the control panel. The login page just refreshes. I’m not sure what happened. I’ve tried these two suggested fixes: http://ellislab.com/forums/viewthread/219568/#1021549 and
http://ellislab.com/forums/viewthread/216012/#999673, but neither worked. I’ve also completely reset my browsers (Safari 6, FFX 14 and Chrome 21)
I’m running EE 2.5.2 on Apache 2.2 using Red Hat Enterprise Linux running Zend Server for PHP (PHP 5.3). The one kink—for security—is that I’ve split the authoring/control panel out to a different server from the front end/production server, but I’m using proxy_pass to fool the authoring server into thinking it’s using the production server.
Thanks!!
