Hi Jaime,
I think you didnt see any error messages because my client has probably removed the Google map from the events. I have added it back to this event: https://www.cestounecestou.sk/podujatie/bratislava-cestami-necestami-24/
I have tried both of the codes in your link, but neither worked – and there was still the error message about inserting Google Maps API twice on the same page.
Thank you for your help.
Lubo
