I’ve just discovered that MiniMax is also conflicting with the new Widgets system in WP 3.9. With MM 3.0.2 active, they don’t work. As soon as I deactivate MM – the Widgets work – i.e. clicking on them reveals a new pull-down menu. With MM enabled, I can do nothing with Widgets.
My site has been converted to display a LOT of pictures via MM – so I can’t just deactivate it till an MM fix comes along. Guess I’ll have to skip using Widget for a while.
