el error es evidente...
Cita: Warning: copy() [function.copy]: SAFE MODE Restriction in effect. The script whose uid is 213347 is not allowed to access /home/vhosts/mipagina.com/nuevo owned by uid 48 in /home/vhosts/mipagina.com/crear.php on line 27
La restricción safe_mode esta en uso... el script con el UID 213347 no tiene permitido accesar a /home/vhosts/mipagina.com/nuevo cuyo UID del propietario es 48
obviamente tienes problemas aun, con los permisos...
