After a long time of talking with MediaTemple support about this issue, I finally received an answer. Hopefully this will help someone else out there struggling with this question, as the answer was nowhere to be found on Google when I searched it originally.
I encountered this issue after creating a WordPress page whose URL was “domain.com/server-status“. When browsing to the new WordPress page, I was greeted with a a “Forbidden” error message.
After some investigating, I tried going to /server-status on my other domains that were hosted with MediaTemple; even domains that did not have WordPress installed, and received the same error message. Going to /someFolder showed a “Not Found” error like it should, but for some reason the “/server-status” folder was forbidden. After the run-around with MediaTemple chat support insisting that it was a user-content error I finally got a phone support technician to verify that an issue existed. They got back to me later in the day with this response:
Upon further investigation, our team discovered that server-status is an Apache configuration that is not configured for viewing on the Grid Server and unfortunately the feature is not available for the service. We apologize that our DV documentation on the server-status page did not state this but are glad to have clarified this situation for you. As you’ve already tested, you would be able to create a similar named directory as a workaround.
All this was basically what I told them to begin with. I mentioned it to the chat support who ignored my theory completely. You can not have a root folder called, “server-status” on a MediaTemple Grid-hosted domain. You can have “serverstatus” or most any other alternative, but having “server-status” is FORBIDDEN!
