I cannot change my avatar. It will not even accept my old spinning disc. This leads me to belive the upload permissions on the server are wrong, as both pics are fully compliant with the width and size-rules.
When uploading from HDD I get the following error:
There has been an error in the upload. Please ensure that the file has been correctly selected and that the upload has taken place successfully.
When I upload to cdfreaks upload and link avatar from there I get
The uploaded file is not a valid GIF or JPG file. Please ensure that it is and try again.
According to Photoshop they are both very much valid gifs and jpegs (tried uploading both formats).
