One-Page Checkout [Support Thread]

[jeking]

I'm pretty sure that that's the root-cause; let me know if that doesn't correct the issue.

No good dead goes unpunished. I can click the button....and now I'm getting the famous "You must choose a shipping method for your order before the order can be confirmed."

In the console, I do see:
jquery.checkout_one.min.js:5 Uncaught TypeError: Cannot read property 'top' of undefined
at o (jquery.checkout_one.min.js:5)
at t (jquery.checkout_one.min.js:5)
at HTMLSpanElement.<anonymous> (jquery.checkout_one.min.js:5)
at HTMLSpanElement.dispatch (jquery.min.js:3)
at HTMLSpanElement.r.handle (jquery.min.js:3)

I don't think I mentioned this, but I'm using OPC 1.5.0
