Just updated to 4.2.7 and our PayPal integration has gone haywire.  In the section where we set the payment options, there's a bunch of code/tags showing up (e.g., mkt_ADMIN_OPTIONS_PK_PAYPAL_LABEL) – they show up in the live shopping cart as well.  

And the Add to Cart buttons keep resetting to 'no buttons' for our non-affiliate products (gift bags and essential oils) – I'm assuming this issue may be related to the PayPal issue?

If you add this item to the cart you'll see what I mean:  http://greengiftsguide.com/store/douglas-fir-essential-oil-by-young-living/

And these ones:  http://greengiftsguide.com/store/category/green-gifts-products/fabric-gift-bags/

We're running the latest version of WordPress:  greengiftsguide.com/store

Any ideas would be greatly appreciated! :)
