The problem is not the recipe but the redesigned FT.com. The recipe gets the links from
http://www.ft.com/intl/uk-edition. The standard sections are up to date, but the weekend sections "Life & Arts" and "House & Home" are not displayed there. This has been an occasional problem even with the previous webdesign.
What you can do: email to
help@ft.com. Report the missing weekend sections, but please do not mention Calibre (it would only confuse them). The more people complain, the faster the issue will be fixed.
