I have create a site which uses a lot of sidebars to create different pages on the frontend. The problem is now every-time I want to edit a sidebar all the sidebars load, and their widgets. You can imagine it take very long amount of time.
I have managed to change the page so non essential sidebars don’t get rendered, but when I save now the sidebars get sent as empty strings, which then detach the widgets from the hidden sidebars.
