I had this once, and it took me flipping AGES to figure it out. I'm not 100% it's the cause in this case, but you are doing the same thing that I did:
When you list members of an object, you put a comma after the last member. Firefox doesn't mind it, but IE does. For example:
Code:
$(function() {
$("#accordion_s2").accordion({
icons: {
header: "ui-icon-circle-arrow-e",
headerSelected: "ui-icon-circle-arrow-s",
}, autoHeight: false
});
});
That last highlighted comma? That's what was causing those errors for me.
