Venue Address & Map: “Oops, something went wrong”

In plugin version 1.4.0, when I go to enter a venue address for an event, the field is blotted out with gray exclamation points and “Oops! Something went wrong.” The code looks like this:

<input type="text" id="loc-address" name="event_address" value="" placeholder="Oops! Something went wrong." autocomplete="off" disabled="" class=" gm-err-autocomplete" style="background-image: url(&quot;https://maps.gstatic.com/mapfiles/api-3/images/icon_error.png&quot;);">

Thanks for your help!
