Map not showing up on Firefox

There is a js error that breaks it “TypeError: Argument 1 of Node.contains does not implement interface Node.”

This is probably caused by the old jQuery version your theme loads. It uses 1.7.2. You should try to load 1.10.2.

You will likely be able to change this in the functions.php in your theme. There is a chance a newer version breaks other scripts on your site, but the only way to find out is to update it.

You can load the 1.10.2 version by adding this to your functions.php, but do remove the old version first.

wp_register_script('jquery', ("//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"), false);

Thanks Tijmen. I tried changing the jQuery to the newer version but, you were right, it broke a bunch of other stuff and the map wouldn’t load in Chrome then either. I ended up changing the jQuery to version 1.8.1 and everything seems to be working now.
