I can't see the threads and posts in my site....
when i get to the thread it's shows like this

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

Please contact the server administrator, webmaster@muyalammavan.com 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.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

can anyone help me to solve this :(

ask your host
500 server errors are usually something on the server end, hence the name :)
do you have a htaccess file?

And did you check your server error log? (If you don't know where they are, ask your host).
