I get the following error when trying to access for the first time:
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [external links are visible to admins only] 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.500 Internal Server Error
I've set the permissions per the instructions and the appear correct both in Dreamweaver and on my site's cPanel.
