Serious problem going on for days now. I just reverted back to amember v3 because new members were being entered into the vbulletin database with the wrong groupID and thus could never login. Also had some other redirect issues. I reverted back to amember V3 and now cannot login even though members are now added with the correct groupid as they were. Other members are having some problems logging in as well. Only other change has been using vb 4.1.9 which I believe was working earlier. Suddenly things just stopped. Most users (I tested this) login to amember, they are logged into amember, but when they get to vbulletin they are not logged in and even trying to post and using the vbulletin login, they are unable to do so. UPDATE - Many more users are now able to login, not sure what cleared up. Apparently it's all the issues with vBulletin 4 which unfortunately nailed the forum badly for several days.
