Loading Map – Please wait…

Hi there,
I have one problem with the maps and the visibility on the frontend.
I have already checked if there are any incompatibilities with the installed plugins, deactivating one by one, but the problem still persist.
I think it depends by some Javascript in the theme I used and I need to insert one map.
What do you suggest? If you need the url or admin password let me know and I’ll give you.

Regards.
