10.5->11.1 Login page blank
I was trying to upgrade from 6.2 to 12.0 and found there is an error in the upgrade script. That is documented by another person. So I set my sights on 11.1. Going to it directly partially succeeded. The site had almost all the data but when I tried to log in, all I got was a blank page. Thinking it was a problem with the DB upgrades I started going through the upgrades one by one.
6.2->6.13 Good
6.13->9.7 Good
9.7->10.5 Good
10.5->11.1 Fails with a blank login page.
We are now running 10.5 but I really want to get to 12.0.
Has anyone else seen this? Is there a fix?
