I upgrade the kentico site version 10 to 11 and rebuild the application and I run the application I am gettiong below error message.
Could not load type 'CMS.Ecommerce.Web.UI.CMSPaymentGatewayProvider' from assembly 'CMS.Ecommerce.Web.UI, Version=18.104.22.168, Culture=neutral, PublicKeyToken=834b12a258f213f9'.
Did you do the code upgrade (and clean and rebuild the solution)? The namespace has been changed to CMS.Ecommerce.CMSPaymentGatewayProvider
I had those few issues too. Did anyone;s got resolved?
Make sure if you have any Class libraries that they are referencing the new files in the LIB folder after an upgrade, otherwise it may try to overwrite the v11 library with v10.
