Google Maps Problem: For development purposes only

i got this yesterday too – allthough i have my billing information allready set for the api, they have to be renewed – because of some changings.
After that all works as before.
So accept and renew billing information on google

If you got that error log with the retired version you can do this to child-theme functions.php til next Enfold update

function avia_maps_version_number( $api_src ){
    $api_src['version'] = '3.34';
    return $api_src;
}
add_filter( 'avf_google_maps_source', 'avia_maps_version_number', 10, 1);
