Payment Form Can’t Be Filled

I’ve seen a few other threads on this topic, but haven’t found a solution. I set Square up and successfully tested it in Sandbox mode, then connected my live account. At some point, the credit card information fields on the Checkout page became unable to be filled (when you click on the fields the text cursor doesn’t appear). I had this on my live site but had to disable it since it wasn’t working and use Paypal in the meantime. My staging site is an exact copy of my live site now, and I’ve enabled the Square plugin and it is doing the exact same thing.

I’m using the latest versions of everything and have cleared my cache.
