Upfront – Editor Not Loading / Google Map Not Displaying

I recently installed Upfront and it often gets hung up (not loading). I have closed my browser, cleared its cache, and even switched computers, but it still does not load properly. Occasionally it works well, but usually not for very long.

Separately, I have tried to add a new region with the Upfront Google Map widget, but it is not displaying. Instead I receive this error message:

“Oops! Something went wrong. This page didn’t load Google Maps correctly. See the JavaScript console for technical details.”

I have tried to create a new page, as suggested in other support threads, but the problem is there too.
