1. Ok
2. I send screenshots.
A panel with widgets is inserted in the first screen. The Main sidebar should be displayed there.
The second screen shows the place of the widget but no WordPress widgets appear. There are only 8theme widgets. For what? (4 screen)
On the third screen is the main page, which is all correct.
