Hello, I installed your plugin for a client in the Philippines and set the map to Philippines. Entering the address failed to locate the address, that is the problem in the Philippines as the road names change so much.
The end result is that the locations can not be set, there is no way to manually set the locations and no way to add lon and lat. Unfortunately this means that the plugin is of no use as we can not add any locations at all.
Such a shame as it looked so promising.
