Hi,
I have a plugin that uses to sort products by stock count,
My plugin works on my local well, but when I installed that on my website I got this error
=================================
Method not found: 'System.Linq.IOrderedQueryable`1<Nop.Core.Domain.Catalog.Product> Nop.Services.Catalog.ProductExtensions.OrderBy(System.Linq.IQueryable`1<Nop.Core.Domain.Catalog.Product>, Nop.Core.Domain.Catalog.ProductSortingEnum)'.
Full message

I solved the problem
The problem was that the plugins I had programmed had a Nopcommerce version of 4.40.3 and our main site version was 4.40.4, and because of this change in versions, the DLLs did not match.
So I deleted all the data except the plugins, WWWRoot, App_Data folders, and Web.Config, then uploaded version 4.40.3 of Npcommers on the host.
The site is working fine now
