After installing Better Frontend Link, it is not possible for many menu-items to edit them. Creating new menu-items is no problem, but modifying gives a "Class not found" error in /administrator/modules/mod_betterfrontendlink/src/Component/Menus/Item.php:112
Unfortunately the preview-link in the top-right in the back-end is not showing after updating the Better Frontend Link to version 1.1.0. This was solved in the development-release.
