EpiServer - HTTP Error 403.14 - Forbidden - Solution

This is very common and can lead to unnecessary frustration.
Basically if no html page is received when trying to call a page it end up being handled as "no access".
So in EPisevers case this often means the site is probably actually working fine.
To fix this just append /episerver to the path and you can probably login then add the host name in
Administrator / Websites hostnames. And it will start working.
