Pay Now on checkout non-responsive, not working!

[ohmyfixpls]

I have received 0 sale for the past week, which is very unusual for my store. I tried checking out with my real credit card, and now I see the problem - the final Pay Now button is non-responsive, does not work at all!

I have already opened up a support ticket few days ago, but they are not getting back to me with a proper solution/fix. What is going on please?

How can this be? Is anybody else having this same issue? Wow!

Did you get a fix? Have the exact same issue. Randomly stops working and then starts working again so hard to catch.
