Smercurio, does turning the autosubscribe feature off resolve the issue? If so, I will give that feedback to Lithium so we can get the bug fixed.
No, it doesn't. But then I didn't expect it to. If anything, the existing subscriptions would all need to be removed. I'm not planning to wade through all 790 pages to delete all of my subscriptions. If you want to delete all of my subscriptions to see if that resolves the login problem, then go right ahead. Fundamentally, it sounds to me like Lithium's software can't handle active users. To be perfectly blunt, Lithium's forum software leave a lot to be desired.
