Hi; I have a similar problem to 'dk-forums.agff.net' as posted today - but viewing other threads wanted to create a separate post as I have not always had this error; only for two days.
I have Coppermine 1.43 bridged with a phpbb forum working fine; except users are now no longer able to upload. All the process appear normal, but a broken thumbnail is displayed instead of the mini thumbnail when choosing an album, title etc - and continuing simply gives the message: "The previous file could not be placed".
I have switched to single file upload and debug info and received the following:
/upload.php
Notice line 2191: Undefined index: user1
Notice line 2192: Undefined index: user2
Notice line 2193: Undefined index: user3
Notice line 2194: Undefined index: user4
/include/picmgmt.inc.php
Notice line 205: Undefined index: OS
Warning line 225: unlink(albums/userpics/10002/thumb_243.jpg): No such file or directory
So far as I can see all relevant directories are 777 enabled, and as I say there are over 200 files in 18 albums previously uploaded without a problem.
If anyone can offer any advice, it would be much appreciated.
Thank you.

Update your gallery.
Thanks for the reply, but I'd prefer to know why the gallery suddenly stopped working - as its been in use for a while and I have other similar galleries on other servers/sites. I just re-uploaded the software which works fine (again).
Then do as suggested.
