Urgente é corretto il mio htaccess?

Ciao a Tutti e grazie per il supporto.
Vorrei un consiglio di un'esperto,perché sto'impazzendo..
ho comprato uno script e lo ho'pagato anche molto caro,il problema é che nel forum ufficiale nn rispondono da giorni e io continuo ad avere errori e dubbi sul mio Htaccess!
Di seguito ne incollo il contenuto.
Vorrei semplicemente sapere se ho'inserito nel posto giusto queste linee che il mio hosting propone in questa guida
http://guida.ovh.it/ConfigPhp

SetEnv REGISTER_GLOBALS 0
SetEnv ZEND_OPTIMIZER 1
SetEnv MAGIC_QUOTES 1
SetEnv PHP_VER 5

Ecco il mio Htaccess..Lo messo nel posto giusto? Ci vogliono i cancelletti davanti o và bene cosi'??
Scusatemi!
