I'm encountering lots of problems with this widget since the latest Muse update (CC 2017). Stacked panels are no longer loading correctly; header and footers are not working properly; child panels are not aligning as specified. I've even changed the structure of the site back to fixed from responsive in an attempt to fix the issues, but no joy. The most I seem to be able to do at the moment is include one parent panel... as soon as I add a second one beneath it, everything immediately goes haywire. Is an update to the widget planned? I have a pressing deadline with a site that already used multiple instances of the widget which no longer work.
