I traced through the bug carefully with The Serised and managed to fix it. I honestly have no idea what was causing it, but for every request she made to the site, a second one was being made to the root of the site http://www.forumwarz.com which would then kick her out of battle for using multiple tabs.

I made my multiple-tab code more lenient and that seemed to fix the problem, although when I switched it over it locked some people out of new forums. That problem should be fixed, but if you can’t enter a new forum try going to this url.

The bottom line is: now the “bug” should be fixed for all users. Please report it again if it’s still not working!
