In order for our LMS to capture your responses to the courses, you can not have third-party cookies blocked. This disables our ability to track your selections.


If you are seeing an error on our LMS that says "SecurityError: Failed to read the "localStorage" property from "Window": Access is denied for this document." please follow the steps below:


Disabling “Block Third-Party Cookie" on the Browser (Chrome) 


  1. Launch Chrome on a new tab in your browser. Select the 3 dots in the far right corner and select 'Settings'.
  2. This should bring you to a list of options. Select the 'Security and Privacy' Option. 
  3. Click 'Cookies and other site data' and select the option to 'allow all cookies'. 
  4. Please return to the course and refresh your browser for the settings to load.
