errore 500 sul server

sno nuovo nn so se è la sezione giusta oggi sno andato a modificare il file htacces.txt in .htaccess ma ora mi presenta un errore 500 sul serve e il mio sito e fuori funzione..... come si risolve???

[alemoppo]

Sicuramente c'é qualche comando errato dentro il file .htaccess.

Io non sono un esperto di htaccess (e nemmeno di altro ), però se lo posti qui, qualcuno ti aiuterà a correggerlo...

Ciao!

a cui alla fine ho aggiunto

RewriteEngine On

Le modifiche che dovresti apportare a quel file .htaccess dovrebbero limitarsi a scommentare

# RewriteBase /

Non dovrebbe servirti altro.
