FYI, the upverter homepage looks like this to me http://i.imgur.com/SFD01HX.png on os x using chrome Version 24.0.1312.52, firefox/safari work fine. Clicking any of the Simulate|PLM|Manufacture buttons does nothing.
Do you have any extensions that might mess with the Javascript? I've seen it working with this exact configuration.
It does this for me too... I use Ghostery. The google+ & analytics requests fail, so you end up calling "gapi.plusone.go();" on an undefined gapi.
Ah, interesting, thanks for the tip. We'll have a fix up online shortly. Sorry about that!
That was it exactly, sorry I didn't have time to draw the proper conclusion myself. Glad tcwc figured it out quickly though.
