Board Thread:Support Requests - Getting Started/@comment-33878615-20160620174520

On a wiki, I tried to log out of my account and edit as an unregistered/anonymous user (just to test, since the wiki never gets unregistered user contributions), but I was immediately prompted to log in and could not edit the article without doing so.

I know that administrators of wikis can request to temporarily protecting their whole wiki from unregistered users editing articles, but I do not think that this is the case. Is there a Wikia feature which makes it so that you have to log in to edit? I am confused.
