Like these ones:
http://ptic.ru/forum/profile.php?id=299 - "normal profile": user has 7 uploaded files (look at last string of profile)
http://ptic.ru/forum/profile.php?id=104 - "bad" profile: user has 4294967294 uploaded files (look at last string of profile)
Why does it happen and how can I fix it?

My English is not good, so maybe it will be hard to explain, sorry. I use PunBB 1.2.17 Russian edition. Users can attach image files to their posts. So there is special position in user's profile, where number of uploaded files is indicated. Sometimes some users' uploaded files numbers became equal to 4294967294, and such users cannot upload any new files anymore. I can fix this problem by resetting files counter for each user one by one. But what should I do for this number doesn't appear at all?

Yes, files, that user had uploaded to server during sending his/her posts. Like pics or photos, and so on.

Hello everyone,
need help on PunBB 1.2.
Number of uploaded files of some users in their profiles becomes equal to 4294967294. I fix it by resetting file counter. But number of users grows up everyday, so it is a bad decision.
Why does it happen and how can I fix it?
Thanks in advance for your answers.
