Hi there,
On my page: any-location-2, I get the following error when I have the Google Map Extender on the page:
Sorry, we have encountered an unexpected error. Please file a bug report (Help -> Report a bug), including error code 1591753412423x489482979013389200 and a step-by-step explanation of how to reproduce this issue.
When I safe preview with no community plugin, this error does not happen.
Also, when I delete the map extender plugin from the page, this error does not happen.
I can continue working on a page with this error for a while until suddenly any google map I add to the page is not visible in preview mode or when published. However, when I hover over where I know the map exists on the page, I can see my cursor changing as it interacts with the invisible map (and yes the map is set to be visible when the page loads).
You are already have access to my app.
