Hi there,
I have upgraded vb 4.2.2 to vb 5.1.6 a few days ago. There is a big problem for some users when they want to log in to site,They are faced with the following message:
You have been permanently banned ...
How can I fix this problem?

Check if those users belong to the Banned Users usergroup. If they are, then move them to Registered Users or other usergroup accordingly.

I check it, They are not banned. These users are all in same usergroup!

Did you modify some PHP code in the vBulletin files by any chance? Or when you upgraded, did you delete all the vB4 files first before uploading the vB5 files?

Delete the content of the IP Ban field under Settings -> Options -> User Banning Options. If entered incorrectly, you can inadvertently ban legitimate users with this field.

I did not this problem in vb 4.2.2. After upgrade this issue is appeared. I have not delete any files of vb 4.2.2.

I checked it. I do not see any IP that is blacked in that field.

When upgrading from 3,x or 4.x to 5.x, you should delete all previous vBulletin files first before uploading the 5.x files. The directory structure in 5.x has changed and this will make sure there are no conflicts between files.
