“Uncaught InvalidValueError: setVisible: not a boolean“

In general, whenever a page opens up for edit or is newly created with “WP Geo” activated, the following error is shown in the browser console:
“Uncaught InvalidValueError: setVisible: not a boolean“
That error is related to the file “http://maps.gstatic.com/intl/de_ALL/mapfiles/api-3/16/5/main.js”, which is utilized by “WP Geo”. The error is causing all other subsequent JS functions to fail and/or is preventing them from being loaded in the first place. When “WP Geo” is disabled, all other plugins work correctly when editing or creating a page.

You´ve an solution???
