 * Looks like PHP on your web host was not compiled with the “xmlwriter” extension.
   This needs to be enabled for Gravity Forms Braintree to work.
 * To enable the xmlwriter extension, you will need to have a chat with your web
   host.
 * Let us know what they say and we’ll provide any further help we can.

 * Marking as resolved, just need to enable xmlwriter and the other required PHP
   extensions (listed below) on your web host 🙂
 * The following PHP extensions are required: curl, dom, hash, openssl, SimpleXML
   and xmlwriter
 * Feel free to re-open the thread if you need further help.
 * Cheers!
