Hello there! I have a place to use Esplanade with child themes. Some days I make changes to the widgets and I can not see if I’m not logged in with my username ago. I was reading and it may be a problem between the main theme and the child. I would appreciate if I can help. Greetings!
PD: Sorry my english.
Sidebar widgets are lost if a child theme is activated. You probably switched between child and parent theme. You can drag widgets to the inactive widgets holder while switching themes and they won’t lose their settings.
