Hei, I have setup addon domain and add files to directory but when I try to open mydomain.com I get next error:

Forbidden

You don't have permission to access / on this server.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

However I can access, http://mydomain.com/index.html ... what is wrong, why doesn't server load index.html when I enter mydomain.com ?

I am using cPanel/whm. Thanks
