Re: [SOLVED]   Pictures (as Attachment) Upload Problem
-----------------------------------
I think it's a CMOD permission problems. 

I say this, because I recently move my forum from one server to other, and NOW all users that were created before the forum was move can't post images. Always have same answer: Only PNG, JPG and GIF extensions are allowed.

Ok, you create a new user, and this user can upload perfectly any image.

If you go to the FTP and check CMOD permissions on new user, are not show, but on users that were created before uploading to new server, has CMOD = 755.

I've managed to change to 777 or whatever, and no success...
