.htaccess

[techno]

Salve a tutti.
sto lavorando su un server di un mio cliente che ha Plesk 9...
Il problema sorge quando inserisco il file .htaccess non lo legge mi da questo errore:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, .... and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Eppure su tutti i server provati funziona benissimo, questo è il file .htaccess:
