Since installing the J4 template Scarlett I can't get the mod J51_Icons to show any icons. I've tried the old & new ways to show font-awesome but I only get a rectangle at the spot where the icon should be. (fa-trophy, fas fa-trophy, fa-solid fa-trophy...) The page-source shows that several css-files of fontawesome were loaded.

The other module J51_InlineIcons works with the icons on the same website.
