I used some shop widgets, they used to be working. However, after some long site inactivity period they broke. Please see the video in a private content.
Polylang is our used multi-language plugin. Trying to disable all plugins except Polylang, WoodMart core, WooCommerce, Elementor didn’t made the widgets work.
I am sorry but I think I may not understand you properly. I tried your shown way to add a widget. However, it’s still not working. Also please check my new video with a steps what I do.
Please make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.
