I just moved two sites where IH was working great to a new domain/host and now I am getting error messages as follows:

Warning: imagejpeg() [function.imagejpeg]: SAFE MODE Restriction in effect. The script whose uid/gid is 608/537 is not allowed to access /home/.sites/93/site37/web/store/bmz_cache/8 owned by uid/gid 48/48 in /home/.sites/93/site37/web/store/includes/classes/bmz_image_handler.class.php on line 651

Is this a host issue? If not, then what shall I do?
Thanks, Amy
