The widget is here http://www.walesdtc.ac.uk/ (there are two widgets – one including the category and one excluding the category) and the shortcode is used here http://www.walesdtc.ac.uk/training/advanced-training-opportunities-across-wales/.
Obviously, global tables mode is switched off!
The shortcode is used in the root blog (I’m not using events in the subblogs yet, just laying the groundwork). I am also using the widget, and seeing the same problem (again, on the root blog).
-77 is displaying all events including those events which use category 77 when global tables mode is on. That is part of the problem.
Yes I have; I should have mentioned that. Unfortunately it makes no difference.
