Error Message for Server Settings

Hi,

I had this idea earlier when trying to disable the Community Server mode from one of my server.

When I did, I got that issue where I was stuck without the ability to Save the settings, and so without the ability to reverse the Community change.

After Email-ing the Support for help, I realized that the error was due of the facts that my servers invites were paused.

What I actually request, is a new error message that pop-up when you are trying to save a settings but that something should be toggled off/on (In my case, the Servers Invite thingy).

I think, imo, that it would be a great feature, and that it would help a lot of people understanding why things doesn't work/save.
