I don't know much about S1 layouts or the coding thereof, but off the top of my head it seems as if something went wrong with the code for friend pages. It seems like it's using the default Classic layout instead of Generator, just judging by the way the top of the page appears. Try checking the section where you choose the base layout and make sure "Generator" is selected for all pages - especially Friends.
If that doesn't fix anything, then try adding a website to the appropriate section of the account's profile. I doubt that would fix it, but some custom layouts for S1 break in strange ways without a website.
