Google Maps StyledMarker no longer working - google-maps-api-3

Question

My pages like this one, using StyledMarker, used to work fine, but since about a month (?) ago fail. Firefox console gives
ReferenceError: StyledMarker is not defined
here
function initialize() { var mapCanvas = document.getElementById('map'); var mapOptions = {center:new google.maps.LatLng(latitudeMid,longitudeMid),mapTypeId:google.maps.MapTypeId.ROADMAP,streetViewControl:false,mapTypeControl:true,scaleControl:true,scaleControlOptions:{position:google.maps.ControlPosition.TOP_RIGHT}}; usefulWidth=window.innerWidth-50; map = new google.maps.Map(mapCanvas, mapOptions); var i; var insertion; var previousMarker; var previousZindex; document.getElementById('zoemCheck').checked=false; for (i = 0; i < fotoCount; i++) {

I include
<script src="https://maps.googleapis.com/maps/api/js"></script>
<script type="text/javascript" src="https://google-maps-utility-library-v3.googlecode.com/svn/trunk/styledmarker/src/StyledMarker.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
I have not been able to find any reference to recent changes in these scripts. Do I need to include a different script?

Answer 1

The URL https://google-maps-utility-library-v3.googlecode.com/svn/trunk/styledmarker/src/StyledMarker.js does not exist anymore.
Most of the projects moved to GitHub but I couldn't find the StyledMarker project on the new site.
But the source can be still be found here and here. Either you replace the line
<script type="text/javascript" src="https://google-maps-utility-library-v3.googlecode.com/svn/trunk/styledmarker/src/StyledMarker.js"></script>
with
<script type="text/javascript" src="https://cdn.rawgit.com/jacopotarantino/google-maps-utility-library-v3/master/styledmarker/src/StyledMarker.js"></script>
or you copy the script into your own project so that you don't have to rely on any repositories to be online (which I would suggest).
