Pro Sites "Sign Up" Button not working

So, "long" history with Pro sites here...when I first started out, everything was working great, and I found a few hacks to make Pro Sites work as I please. I change my website theme to UpFront, and everything breaks, as I am sure you are all aware of Pro Sites not working with UpFront. So, I change back to my old theme that I used before.

Now, the pricing table is not lining up, and one of the hacks which I used previously (Found here: no longer work. And the worst, if I click on "Sign Up", it does nothing, where before it brought the sign up fields. Perhaps this all broke with the recent update a week or two ago?

I have gone ahead and granted support access. I have waited too long to launch my website.

Please help me resolve these issues.
