When clicking "Ship" or "Update Costs" in FedEx shipping manager, the following error occurs:
"Received content of invalid Content-Type setting: text/html - SOAP expects "text/xml" 4."
This is normally a temporary issue with FedEx or Shipping Manager servers that will resolve on it's own. Try again later to see if it has resolved.
If you are unable to try later, you can sign in to your account at www.FedEx.com and print your shipping labels there.
