Avatar and Siggy problem

[Xerixe]

Hey guys, when I try to upload something via website,
I get this error

Upload failed due to failure writing temporary file.

And when I upload an animated signature, it gets turned into a JPG file.
The siggy gets saved to the site but it won't be animated anymore :(
Anyone know why?

Check your error_logs. Perhaps you don't have a /tmp directory properly set up. You can look at your phpinfo and see what it says there. You may want to also go to maintenance > diagnostics and upload a file there and see if there are any errors.
