Hello @Tiger,
Sorry for the delay in answering, our technicians team doesn’t work during the weekend.
Do you have same problems when a default theme (like Storefront, go to Appearance > Themes > install and activate WooCommerce default theme Storefront) is activated on your site? Please check and let us know. Widgets could be messed up after switching, so open the Appearance > Widgets tab before switching to be able to move the widgets to the correct area after switching back.
Regards
