Try changing your theme.
Stripe Pro Form - Somethings strange here. Help Me Please
Yes, multiple themes… 
No luck though. Same results. Removed any MU plugins too.
I told you debugging javascript was hard!
I’ve taken another look. Putting what I can see with what you have told me about your own debugging efforts, I am now pretty sure it’s something you have set in s2Member which is causing javascript to behave like this.
How do I know? If I keep javascript enabled but add some CSS in my browser to make the fields appear, it is clear that they are disabled. In fact, the fields are even showing as disabled="disabled".
That is why s2Member doesn’t show them. So you must have set them to be disabled somewhere. So you need to go through all your settings again to see what you have turned off or disabled.
That makes sense. I will take a look at it again. I had to walk away for a bit. I really appreciate you taking the time and helping me figure this out. I will let you know what I find. Thank you.
I’m not for sure what happened but it seems to be working now. Thanks again!
