Why is my Map facet suddenly not working anymore?

There is a known bug in Google Maps version 3.62, which unfortunately is the version used by the quarterly channel that FacetWP uses.

Until Google fixes this bug, or we switch to the weekly channel, you can fix the issue by adding the following snippet to your (child) theme’s functions.php. At the time of writing, this will make the map use Google Maps version 3.63:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_filter( 'facetwp_gmaps_params', function( $params ) {
  $params['v'] = 'weekly';
  return $params;
});

Without this fix, your map will not show markers and will default to showing Africa, accompanied by a Console error message containing: “addEventListener is unavailable in this version”.

Note that this fix is only needed when using the new, built-in Map facet. Not when you’re using the Legacy Map facet add-on.
