   Hi
   Just can't find this:
   To make something show up in specific categories, I've tried this code - but what is wrong?
   Thanks a lot for any hints,
   Kjetil
   'is_category(4,5,6,8,9,10,11,13,16,21)'
   or - also on the categories' sub-pages: 'is_category(4,5,6,8,9,10,11,13,16,21) || (is_single() && in_category(4,5,6,8,9,10,11,13,16,21))'

   Thanks Moshu
   That was the link I couldn't find, or - actually - that page contains a link to the crucial explanation.
   The necessary code to make eg a widget show up only on these categories' pages (by the use of the Widget Logic plugin) is:

   in_category(4) || in_category(5) || in_category(6) || in_category(8) || in_category(9) || in_category(10) || in_category(11) || in_category(13) || in_category(16) || in_category(18) || in_category(21)

   -

   is_category(4,5,6,8,9,10,11,13,16,21)

   is not allowed, it says.
   Thanks,
   Solved.
