Recently updated to 1.8.11 on a 1.5 joomla website and i am having issues with batch geocoding. For some reason the update did not retain any geocoding information on our 1218 locations and i have to batch geocode them again.
But for some reason i get a 403 Error when it hits the very first row:
It's also possible that it may no longer be working. Google has been making continuous breaking changes, now requiring API keys for Geocoding, a Billing Account setup with Google and specific Services enabled per key.
We have not been maintaining the Joomla 2.5 versions so It's possible it finally broke compatibility.
