The tabbed plugin would be perfect if it showed up where I need it...
It does show up on special pages, including the category archives but not on the posts themselves. If I tick the relevant box on the the special pages tab the widget still does not appear on 'all posts'.
I'm concluding that if the widget can appear on the category archive pages (after ticking the relevant box on the special pages tab) then the widget is able to register which categories are ticked but then simply does not activate itself on any posts. This may help to clarify where the code needs to be tweaked?
I will take a look inside the code to see what I can find but I don't think I'll get anywhere. Any suggestions - please help!
