I’m having the exact same problem, except that I’m not trying to trigger the “addAddress” function with a string of meta values but simply my post’s title which is always in the format of “City, State”.
From what I can tell, the plugin looks like it calculates the geo coordinates using this site: https://api.local.yahoo.com/MapsService/V1/geocode?appid=YahooDemo&location=
And that site has no problems when I manually type in “City, State”.
For some reason Phoogle isn’t passing along the correct addAddress info. It must have something to do with the code inside the addAddress function but I’m not a coder so I have no idea. ??
