When I want to add my user picture, the picture can't upload and when I inspect it the link is broken and get this error:
Warning: array_key_exists() expects parameter 2 to be array, null given in theme_image_formatter() (line 605 of /home/webpenir/public_html/modules/image/image.field.inc).
However, when I add a picture for another user, it works pretty good.
how can I solve this?
EDIT
Only user 1 can't upload but other users can do, which is really strange.
