The icon images are not displaying only a rectangle where they should display. I can click on them to go to the locations I set them to. I can see they are called in the fontawesome-all.min.css file. I would also like to change the icons to be youtube, instagram, spotify and whatsapp instead of the default ones. In fact all of the icons are not displaying. The hamburger menu icon, the return to the top double arrow icon and the email.png are not displaying.
