I am trying to install drupal however I can't get to the installation screen. I installed the database and now when I go to the url I get error 500 (The server encountered an internal error or misconfiguration and was unable to complete your request.) I have DYDNS on my server...I don't know if this is screwing it up. I also have ISPconfig but the server has been configured for months with no known issues so any thoughts or suggestions would be great.
