RESOLVED NOW: Proceed To Checkout button not working

[paigehb]

RESOLVED NOW: I was able to download a fresh copy of my theme and publish it and now my Proceed To Checkout button is working again.

Hi-

My website is A Colorful Farmhouse and I am on the Masonry theme (with Installments message). 

My website checkout had been working fine, or so I thought, but recently I have had several customers contact me through Shopify Inbox and tell me they are having difficulty when trying to check out. If they click on More Payment Options from a product page, it takes them to a regular checkout page- no issues. But if they go to their cart, the Proceed To Checkout button is not grayed out and looks like you can click on it, but when you do, nothing happens. So they are forced to use one of the Express Pay options listed right under the Proceed To Checkout button. That is causing some confusion and some customers don't want to use one of the Express Pay options so I end up having to help them place the order and send them an invoice to pay from. Can anyone help me on what could be wrong with my Proceed To Checkout button? Thanks in advance!
