docs.doctrine-project.org external links broken

[Arkemlar]

Some links like this one: http://docs.doctrine-project.org/en/2.0.x/reference/configuration.html#reference-proxies now broken due permission denied error.

Permission Denied

You don't have the proper permissions to view this page. Please contact the owner of this project to request permission.

There are more links with same error (but I lost them in messed up browser history). Pretty weird error.
