We have recently updated the icon library to use the latest version of the ionicons.com icon font. This may have caused an issue on your site with icons not displaying correctly.
Please refer to their website for the latest icon class names. For example the avatar icon no longer displays, you will need to find a new icon that replaces the original for example “ion-ios-person” then you would replace the class name in the menu “CSS Class” field.
