Forum Image Upload Problem

[محروم.كوم]

I keep getting this error whenever I upload an Avatar :

Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File() is not within the allowed path(s): (/home/camangan:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp) in [path]/includes/class_dm_userpic.php on line 204


Warning: fopen() [function.fopen]: Filename cannot be empty in [path]/includes/class_image.php on line 333

Does anyone know why? or how I can fix it? __DEFINE_LIKE_SHARE__
