Problema con subida de files

[yeku]

Hola amigos, saben interpretar este error que me responde en el foro cuando intento subir un file determinado:

Warning: mkdir(): SAFE MODE Restriction in effect. The script whose uid is 10025 is not allowed to access /var/www/vhosts/forodealcorcon.com/httpdocs/files/1/3/4 owned by uid 48 in /includes/functions_file.php on line 112

Eso me ocurre en mi foro, es vbulletin.
