What steps will reproduce the problem?
1. Open Map
2. ^^
3. ^^

What is the expected output? What do you see instead?
The map is supposed to load, but insetad I get a lua error.  When MA is disabled, the map works fine.  It worked fine over the weekend as well, when I logged on monday was when it started not working.  It used to display the map frame/coords without a map, but now it displays nothing.

What version of the product are you using?
The most recent - 15.0.6

Do you have an error log of what happened?
