Error Line in Admin panel

[lordi]

hello

when I enter to my Admin panel, I find the following error

Warning: filesize() [function.filesize]: stat failed for ./../data/media/.../s in /home/content/xxxxxxxxxxx/html/photos/admin74/admin_functions.php on line 661

So

I went to the admin_finctions.php file on line 661 and found this line


$size += (is_dir($dir.$file)) ? get_dir_size($dir.$file."/") : filesize($dir.$file);


*** http://[b]note: everything is opening fine, but this error line is appearing in admin[/b]


any clue ?
