My Primod SEO based forum was worked fine,but during some problems,when I try to change .htaccess and create a new one,this problem occures only in index.php (Forum index).
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster and inform them of the time the error occurred, and anything you might have done that may have caused the error.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
This error occures in forum index and other areas (topics,...etc) working fine !
The server is a share host and I do not have any Shell access
