Unable to redirect to Paypal at checkout because of duplicate id _wpnonce

Hi,

My checkout page throws this error anytime I want to proceed to Sandbox Paypal, making a purchase. As it involves fbevents.js and checkout.min.js it could be a bug caused by Woocommerce or PixelYourSite’s plugin which adds a FB Purchase Pixel to checkout among others. Also I’m using their other plugin for creating FB product feeds.

The error the checkout returns after clicking on Proceed to Paypal is:

SyntaxError: Unexpected token D in JSON at position 2

When checking the tool XHR and Fetch the console throws these js errors:

[DOM] Found 2 elements with non-unique id #_wpnonce
<input type="hidden" id="_wpnonce" name="_wpnonce" value="b54635f4c7"> and eb9f44e055
Unable to fix malformed JSON | checkout.min.js
Resource interpreted as Document but transferred with MIME type image/gif facebook.com/tr | fbevents.js

Also when I check findgoodhealth.org/checkout/?wc-ajax=checkout the page throws this text:

{"result":"failure","messages":"<ul class=\"woocommerce-error\">\n\t\t\t<li>We were unable to process your order, please try again.<\/li>\n\t<\/ul>\n","refresh":true,"reload":false}

Console doesn’t return anything.

Thanks for the attention and I hope we can fix this.
