Are you having troubles with the Table of Contents in your course (circled below)?

"Out of the box," current versions of Chrome, Firefox, Edge, or Safari will work perfect with WCLN courses.   

Given that, sometimes you may visit sites with pop-up questions and unintentionally block "third-party-cookies," which causes problems with your course.

For Chrome, you can check this by:

• Within Chrome, go to chrome://settings/cookies (can paste into URL)
• If you have "Block third-party cookies" or "Block all cookies," that's a problem.
• Instead, choose "Allow all cookies" or "Block third-party cookies in Incognito" as shown below
