I have a MU install, the admin for my main site (site.com) shows the Featured Image Meta Box, but the admin for the subsites (site.com/blog1) the F.I.M.B. is not shown or available in the screen options tab..
The sites run the same theme and with the same settings. The sites both run a (the same) child theme, and the
is defined in the Parent theme (framework).
It's like the
add_theme_support('post-thumbnails'); only has effect on the main site in my network..
is this a known problem, or should I start to dig for bugs in mu setup?
