I did integrated following https://xenforo.com/help/google-integration/ It runs normal on most of OS. But not in my new Mac - Yosemite (10.10.4). This is the error on console: "Uncaught ReferenceError: gapi is not defined". So it makes the register/login screen could not load on overlayloader. And I could not register with Google or link with Google account in my forum's account. Is there any problem? I tried with my other Mac - Mountain Lion (10.8.5), it works normal.
