Appointments+ on Scribe theme is not working at all

have appointments+ installed, and everything is setup for it. But I go to add it to the website (through add widget) and it keeps saying "Ooops, something seems to have gone wrong with rendering the widget," regardless of whether or not I add it on the front end or the backend.

I'm using the Scribe theme - which is a WPMU DEV theme. For the widget side, I have been using the Upfront editor and drag and drop the widget and then select Appointments+. I have also tried going in the backend and selecting it, but it says the same thing.

I am using we the current versions: 1.2 for Upfront and 1.1 of Scribe.

As for the server, we are using a standard GoDaddy WordPress installation
