If you have Compatibility View turned on when accessing the KnowBe4 site, it can cause issues that will prevent you from properly viewing training modules. Compatibility View essentially makes your browser interpret a website as if you are using a much older version of Internet Explorer.
To properly view the training, you should always use the latest version of the browser you're using. So you'll need to make sure you are not viewing the KnowBe4 site with Compatibility View enabled.
To turn off Compatibility View, click the gear icon on the top right of your browser, then click Compatibility View settings.
Selecting Compatibility View Settings
If KnowBe4 is listed under the Websites you've added to Compatibility View list, click Remove to remove it, then click Close.
Compatibility View Settings
If this does not fix the issue immediately, there is another setting you should turn off called Display intranet sites in Compatibility View. Open Compatibility View settings again, uncheck this box, and click Close.
Uncheck Display Intranet Sites in Compatibility View
Disabling Display intranet sites in Compatibility View generally applies when you are using a proxy for internet connection and have bypassed the proxy for connections to training.knowbe4.com or eu.knowbe4.com (usually done for Phish Alert Button compatibility). The reason for disabling this setting is that by default, Internet Explorer thinks any site on the proxy bypass list is an intranet site and will display that site in Compatibility View unless Display intranet sites in Compatibility View is disabled.
