Now virtuemart show feature products on home page order by random. how can i show feature products in homepage order by last added products?
You can enable 'Show latest products instead of 'Show featured products' in VM configuration > 'Templates' tab > VirtueMart Home Page Settings.
And select "Last created products first" in 'Latest Products - Sort order of display' in the 'Shopfront' tab > 'Product Listing'
