groupthumb error

[vanni77]

Hello everyone,
I have a problem with my vbulletin 3.8.3 (original file)
The problem is with the social groups but in general with the images uploaded to the server.

Error:
http://www.forumsalute.it/community/image.php?groupid=1&dateline=1263219081&type=groupthumb

while without groupthumb displayed correctly

There must be some problem in function groupthumb
in your opinion, what?s the problem?
Thank you very much and sorry for my english
Vanni

Are you storing your images in the filesystem or database? If in the filesystem, what are the permissions on the thumb folder for the group images?

If the permissions are fine, also take a look at this page from the manual about troubleshooting blank or 'white' pages: http://www.vbulletin.com/docs/html/blank_pages
