Hi all,
I developed some new plugin in version 2.6 and I have always the same message about the configuration view:

Any suggestion please....

Thanks in advance

Massimo

did you add the route for the configuration? something like

routes.MapRoute( "Plugin.Payment.CartadiCreditoOffLine.Configure" ,
"Plugins/PaymentCartadiCreditoOffLine/Configure" ,
new { controller = "PaymentCartadiCreditoOffLine" , action = "Configure" } ,
new[] { "Nop.Plugin.Payment.PaymentCartadiCreditoOffLine.Controllers" }
                ) ;

Add the appropriate names and namespaces

Yes I did ... The problem will be in other side..

did you marked your views as embedded?

Sorry .. How I can define a view embedded? I think it should be a right suggestion but please clarify me if possible..
Thanks

in Visual Studio, select the view, next in the properties windows set the build action as "embedded resource"

I suggest you start looking at this:
https://www.nopcommerce.com/docs/77/how-to-write-a-nopcommerce-plugin.aspx

this will save you a lot of time.

I will try with your suggestions ... I have already created some plugin in nop commerce 2.5 and before.
Now I tried to duplicate one of this old plugin and it does not works .. Probably will be a stupid issue but the solution is not so easy ..

Thanks again.

View as "embedded resource" solved the issue!!
Thanks to all you .. fantastic !

Many thanks
