Hi @mvital

This issue is very strange the above code should be able to work. You should try to investigate whether there could be a plugin conflict that could be affecting the loading of the map on the front end.

I would also suggest using an iframe to try and display the field using the following example code:

<iframe width="400" height="400" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.ca/maps?center=<?php the_field('mapa'); ?>&q=<?php the_field('maps'); ?>&zoom=14&size=300x300&output=embed&iwloc=near"></iframe><br />
