I am trying to setup widgets in SS3.1 with the Simple theme. The Blog widgets appear OK now that I have added the code for widgets on all pages and added $MyWidgetArea to the layout. They didn't appear when I used the Blog/Widgets instructions.
I used Composer to install SS and the modules.
Could you please recommend widgets that are known to work with SS3.1 so I can track down where I am going wrong. At the moment I don't know if it is me (likely) or the widgets! (I have tried several widgets with varying errors).
