It was caused by a bug in Safari, which caused it to fail when the XR names contained spaces.

An alternative workaround for an existing rendering like the example here is to percent-escape the “folderName” value in the .html-file. This basically means to replace all space characters with “%20”.

E.g., for the example given here, in the file “Best Hardtop Complete_XR.80.html”, replace the line


var folderName = "Best Hardtop Complete_XR.80";

with this:


var folderName = "Best%20Hardtop%20Complete_XR.80";
