Sorry about that. I no longer have access to a SP 2007 test site so I cannot get proper testing done.
This means SP 2007 support is slowly fading in new versions…
You can try adding this function to your spjs-utility.js file in “/SPJS/DFFS/plugins” folder:
function makeAbsUrl(a) {
if (a.length > 0 && "/" == a.substr(0, 1))
a = window.location.protocol + "//" + window.location.host + a;
return a
}
This is a built in function in SP 2010+ and I thought it was present in SP 2007 as well.
