Invalid Referrer. Error: 4003

This error means that you have all the correct account details, but a setting in your control panel is preventing you from running internet-based transactions. To fix this:

  1. Log into your control panel: https://www.myvirtualmerchant.com/VirtualMerchant/login.do
  2. Click Terminal>Advanced>System Setup
  3. Un-check the "Use HTTP Referrers" setting.
