Hello Peter,
In the backend my google maps renders perfectly (autofills with address, can see map). But in the front-end, it looks like this: https://www.staging109.acume.org/geo/
(I removed all plugins and changed to WP default theme)
I did have custom JS, which I tested, then returned back to checking the plugins and I think something went wrong in my initial check (perhaps forgot to clear cookies or cache) as it is something in the perfmatters plugin! Thanks!
