Error Message: Internal error 4451 (DomName not supported)

This error message is displayed for any of the following reasons:

  • You are running the Web Viewer in an iframe.  Iframes are not supported as the Web Viewer must run in its own domain.
  • You are running a proxy which has optimization settings enabled (e.g. saving scripts locally etc.).  This is not supported for security reasons – everything must run from our website.
