I’m upgrading my database from 1.3 to 1.7 with a fresh install. All seemed to work well but when I hit the admin screen and try to log in, I’m taken to a broken page with no real error. Everything I have found suggested I edit app/code/core/Mage/Core/Model/Session/Abstract/Varien.php to comment out a few lines or change but that didn’t see to do the trick. I’ve checked the core_config_data table and my URLs are both http:// but I notice when I log into the admin it is redirecting me to https:// which may be part of the problem?
Perhaps I need to comment out a different set of lines in the afore-mentioned file in 1.7.
