Some of my members cannot login to the vB forum after I upgraded my aMember install from v3 to v4. There are other issues with the upgrade as well and I've started threads and support tickets about them. Unfortunately I've not heard back about any of them yet. As this is a time sensitive issue I was wondering if the best course of action would be to downgrade my install back to v3, if that's possible. If so and I can get it working again I'd happily do that and worry about the upgrade another time. But I really need this fixed today as I'm scheduled to leave out of town tomorrow morning. Not good timing at all... Any thoughts on fixing this or how to revert back to v3 would be appreciated. Thank you
