marker icons do not show up with IE8 WordPress


a customer of mine uses my mapping plugin to display a route together with several custom points of interest - see demo at

In constrast to modern browser (please check with latest firefox or chrome), the markers - in contrast to the gpx route - do not show up with IE8 and I do not have a clue why :-/

Any help/hint is appreciated!

Bob answers:

The issue is IE8 is not creating img tag for marker at all.

which version of leaflet you are using?

Bob comments:

Please try by adding "iconurl" parameter.

There is also one error on page

using leaflet v0.7.3 - regarding extra comma: will try that thx

Bob comments:

The trouble is with ajax request with IE8.

Bob comments:

This condition become false if (xhReq.readyState === 4) . xhReq.readyState returns "undefined".

That's why your marker related code is never executed.

thanks - that was the issue.

I replaced .onload with .onreadystatechange and now it also works with IE8! :-)

I think its because the marker is a PNG..

Robert Seyfriedsberger comments:

thanks for your reply, but unfortunately this is not the reason for this issue, as maps with icons and without gpx tracks are being shown correctly
