ositive on "[Plugin: Events Manager] Problem with map in front end input form"

Hi! First of all thanks for your great plugin.
I created google maps API KEY following the instructions of the follwing link:
http://wp-events-plugin.com/documentation/google-maps/api-key/

When I create an event from admin page the map is shown correctly, but when I open a front end input form from inspection page I see 2 waing, and when I try to insert address data same errors are generated (for each input I try):

waing:
Google Maps API waing: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
util.js:210 Google Maps API waing: InvalidKey https://developers.google.com/maps/documentation/javascript/error-messages#invalid-key

error:
this service requires an API key. For more ...

Any idea about why I get this waings/errors?
Thanks!

Hi,

If it's working OK in the admin area, it's possible there's a conflict on the front-end caused by your theme or another plugin. To check if it is, can you test with all other plugins deactivated and while running the default WordPress theme?

Yes! was a conflict with GEO my WP plugin
Any possibility to solve this conflict as I would like to use both Event Manager and GEO my WP plugin?
Thanks
