I’m not sure without knowing more about how you set it up. However, I am seeing these errors in Safari:
[Error] TypeError: ‘undefined’ is not a function (evaluating ‘element.attachEvent(“ondataavailable”, responder)’)
observe (prototype.js, line 5644)
_methodized (prototype.js, line 438)
[Error] TypeError: ‘undefined’ is not a function (evaluating ‘element.dispatchEvent(event)’)
fire (prototype.js, line 5734)
_methodized (prototype.js, line 438)
fireContentLoadedEvent (prototype.js, line 5820)
You also seen to be using WowSlider, which uses JQuery. The TransitionFX Actions use Scruptaculous and Protaculous. These two libraries are known to clash, which is why it’s not working.
There are ways to get JQuery to run alongside Scriptaculous, but you’ll probably need to ask the WowSlider people how to run their software in JQuery’s non-conflict mode.
Another good way to sandbox WowSlider from the rest of your page is to put it in an iframe. Lots of people here have done that with good results, I think it’s one of the primary techniques they offer on the export side.
