Hello,

In order to get images have been cropped as per Woocoommerce settings, it is necessary to remove the sizes inside image widgets: https://prnt.sc/217vpo5

As for the sidebar, this is WordPress but: when you switch the theme, the widgets are reset. When the sidebar is empty it is not shown. https://prnt.sc/217vzrx

If you have any questions please feel free to contact us.

Best Regards
