Ok. I did some work yesterday and was able to get site to stop forcing a log off. The bottom line: I had to load version 1.5.2
I started by removing all styles except for the default vbulletin style. I then disabled all plugins (except for yours) and was still being logged off. I then uninstalled v1.7.1 and installed the most recent prior version. The problem continued through all of the versions except or 1.5.2 (which I originally had installed)
The site isnt open yet so there hasnt been much activity. I originally installed vb3.8.1 and have since upgraded to 3.8.2. I have made a couple edits to php but nothing major. I kept a short list of any of the changes. Here is the list I kept:
Other than these edits there was nothing changed from the base vbulletin 3.8.2. No styles, or plugins and the other versions still didn't work. I am ok with using version 1.5.2 but thought the feature with the cookies was nice. Do you think something above may be in conflict?
