I installed the Sitecore Commerce 9 update 1. I followed steps from this site
After successfully installed powershell script without errors, I tried to open storefront.local/ site and managed to see demo site. However, when I try to open Experience Editor I don't see items from the demo site, I just see empty Experience Editor. Check screenshots.
When I open storefront.local/ and do search, I get error page "There is no method 'FacetOn' on type 'Sitecore.ContentSearch.Linq.QueryableExtensions" I assume that something is wrong. I think I did post installation steps correctly. Can anyone help me with this?
