Yes, it doesn’t currently work.
I’m not sure what I got myself into, but I whipped up a key for myself and dropped it into the .js file – that got it working again.
I recall that being free in the past, but now it seems they will try to charge me at some point?
In any case, perhaps an option for users to enter their own google maps API key could be a solution? I assume if we all use YOUR key, they’ll definitely charge you (high volume plus youd have to leave it unrestricted.)
Due to abuse of the geo IP feature (from another plugin, I believe), this will be removed in the next version. It may return once I can spend more time preventing the abuse.
