It also doesn’t load for me in Chrome, but I do notice this error in Firefox ( doesn’t show in the Chrome developer tools, but it could be the reason it breaks ).
Loading failed for the <script> with source “https://maps.googleapis.com/maps/api/js/QuotaService.RecordEvent?1shttps%3A%2F%2Fhairborist.nl%2Fkapsalon%2F&3sAIzaSyBdzZKUsfUUYnme2cnk6WNjiuZYteau1iU&7se8thot&10e1&callback=_xdc_._xwusrt&token=127439”.
Are you using any other plugins that use Google Maps? If so then try to disable them, or if your theme is loading the script, then try to remove it ( most like done from the functions.php inside your active theme folder.
You can also try to enable the compatibility mode on the WPSL settings page ( tools section ).

It does have something todo with the other map, but maybe in combination with Cloudflare.
You can disable Cloudflare, and the map options in your theme? The error comes from another Google Maps script, so maybe when you changed it you still saw a cached version?
