Thread:Extension talk:GoogleCustomWikiSearch/No Results

I get "No Results" when using this extension. I'm using MediaWiki 1.24.2 and I've tried the 2014-12-02 build of GoogleCustomWikiSearch (from here) and the latest build (today, 2015-05-15, from here). I've toggled every setting I can find, making sure to check the settings file for both versions for the proper global names. Further, I have tried I see similar extensions have similar problems, but this one can't be fixed by the same things, e.g. removing all white space from Google's code. What am I missing?
