den här fungera för mig när jag prova scriptet för några veckor sedan, har ej orkat prova den igen innan jag posta det här inlägget...


EDIT

Jag har ej kodat scriptet.

Om det nu skulle vara så att det inte fungerar så kan det mycket väl vara så att IPet är bannad på ditt webbhotell.

Prova precis scriptet vilket fungerar ...
