Adobe Audience Manager security error (DOM exception 18): protocols, domains, and ports must match
While loading a page, errors, also known as Demdex calls, appear in the console.

Issue

A typical error:

"SecurityError (DOM Exception 18): Blocked a frame with origin \"URL" from accessing a frame with origin \"Demdex subdomain URL\". Protocols, domains, and ports must match | Audience Manager

Environment

  • Adobe Audience Manager
  • Demdex calls
  • Browser console

Cause

This error also occurs in other browsers because jQuery.animate() sometimes tries to manipulate all frames on the page, causing a cross-domain security error in the iframe.

Resolution

If jQuery.animate() is being used, consider disabling its use temporarily to see if the problem goes away.
