Parently when using kiwitrees theme the page menu-icon from webtrees shows up. And in the stylesheet it also gets the menu-icon from webtrees-theme. I dont know how the F.A.B theme handles it or in your own greystyle about the menu icons. Meaning in themes without menu-icon it should not appear in the themes 🙂
Atm the problem is solved by editing the css file 🙂
admin and owner of a user customized version of kiwitrees (contain 3 family trees)
Looking at that link I can see no menu item for simpl_pages, only two copies of simpl_menu (simpl_menu2 and simpl_menu3). Does he have simpl_pages hidden for members only? Please confirm, and if he does I will need temporary access to view the problem.
With his simpl_menu2 he needs to add a kiwitrees theme file with a style.css included. It looks like he might have one for simpl_menu3, so he can copy the same one to the other version. That will remove the icon from his menu item “Internet links”.
