Hi,
I was able to track down the problem and fix it here. I will release a fixed version in the next few days. The problem was a bug that was causing the div which contains a map not to have a width and height style rendered so it effectively has 0 height and therefore becomes invisible.
There is still a problem with the google map service, but only for Satelite view. This was causing me to think the general problem was with the service, but after you said that reverting to the previous version of mojoPortal solved it, I tried the demo site which is running an older version and sure enough the map works there albeit the satellite view doesn't work. So after more investigation I discovered the width/height not rendering issue as the main cause of trouble. Fixing that got the maps working again here locally.
Best,
Joe
