Can't refund after migrating to new server

[brideoflinux]

Last week we migrated our site http://unicornshoppe.com to a new server with a new IP address. We are using Zen Cart version 151. This morning I discovered that I can't make a refund from the order edit screen via PayPal express. After attempting a partial refund, the page reloads as normal, but nothing from PayPal indicating the refund has been made. On logging into our PayPal account, there is no indication that the refund has been made.

The order we're attempting to refund was placed after we moved to the new server. This feature was working perfectly on the old server. We use a VPS, so we have total access to the server.

This problem seems to have resolved itself. Sorry to be a bother.
