Google maps is blank

Hi!

Out of the blue Google maps is no longer working on our website. The Google map element is blank.

When I check via the developers console it returns 0

<div id=”av_gmap_1″ class=”avia-google-map-container ” data-mapid=”1″ style=”height: 400px;”></div> == $0

I has worked until this week.

What I have done to fix this problem
– Checked the settings in Google developers console
– I have created a new API key
– Checked if Google maps works with another plugin, it does!
– Disabled all used plugins, no difference
– Restored an older version of enfold, no difference
– Check enfold child settings with other websites I have build with enfold, no difference

I have read about adding action

add_action(‘init’, function {
update_option( ‘av_gmaps_api_key’, ‘ADD KEY HERE’ );
});

But I have no idea where I have to ad this code, functions.php?

I hope you can help me out.

Kind regards,
Sebastiaan
