Map shows just a grey color

Having the dame issue. This plugin went from easy to difficult overnight.
Anyone out there have an easy solution to the grey map on this page? http://144university.com/things-to-do-in-tucson/ sure would be appreciated.

Hi,

I followed the advice in this page: https://wordpress.org/plugins/nearby-map/faq/

In the theme edit area Copy & paste the code to the top of your theme “Theme Functions” functions.php. Be careful and use a child or staging or use a back-up

Is there a way to use another tile provider than CloudMade ?
Yes, there are other tile provider than CloudMade (used by default in this plugin). To chose for another, simply paste this function into your functions.php.

<?php add_filter( ‘maps_datas’, ‘function_for_alter’ );
function function_for_alter( $maps_datas ){
$maps_datas[’tiles’] = “http://{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.jpg”;
$maps_datas[‘attribution’] = “attribution I want/use to show”;
$maps_datas[‘subdomains’] = array(‘otile1′,’otile2′,’otile3′,’otile4’);
return $maps_datas;
} ?>
