I think you’re asking about the geocoding settings on the MapPress settings screen.
I’m not sure why you needed the extra code. It looks a lot like what’s built into the ‘mappress_meta.php’ file, which also watches the meta events, and updates the map if the meta values have changed.
Maybe it’s something to do with ‘pods’ (I’m guessing that’s a custom fields plugin?). Anyway, I’m glad you got it working.
