After logging into Ektron while using Internet Explorer 11, the Ektron toolbar is not appearing on your site. Instead, you're seeing the PageBuilder toolbar.
Please Note: This issue ONLY applies to Internet Explorer 11.
This behavior is occurring because of IE11's compatibility view being turned on by default. This configuration isn't actually supported so to help avoid odd functionality and cosmetic issues, you'll want to turn compatibility mode off.
Here's how to do that:
1. Press Alt/X to display the Internet Explorer Tools menu. Alternatively, you can click on the little gear like icon in the top right corner and find the option there as well.
2. Select Compatibility View Settings
3. Uncheck "Display intranet sites in Compatibility View"
