Square Checkout Form Not Working

I'm having an issue with my Square checkout form not working. Clients can create an account but when they get to the payment screen they aren't able to type anything in the boxes at all.

I am still using version 3.5.3 (I know, I need to upgrade, I just haven't gotten around to actually doing it). It quit working a couple of days ago. Nothing has changed. I've called my webhosting company - they can't find any issues but suggested I revert my PHP back a version so I did that and still no luck.

Any ideas on what could be wrong or suggestions on how to quickly get back up and running? This is my busiest time of year and I have many people emailing me that they can't book a session on my calendar so I really need to get it figured out ASAP.

Thanks so much!

You're right, you need to update to the newest version of sytist to continue taking payments via square.

Recent changes with square payment requires the newer sytist version.

Asap? - always have a backup paypal account and switch payment types in sytist. Hopefully your version of sytist is still compatible.
