Hi
We are having the a similar issue. The Google Map on the Event page shows the map correctly. But clicking on the link “+ Google Map” just opens the a map of the USA.
See here: http://www.fsdf.org.uk/event/fsdf-f-gas-summit/
Upgrading to version 3.9 does not resolve the issue. I think the error is linked to how the URL is encoded.
Look forward to your reply.
