I have a ridiculous question about master pages in asp.net. I have several pages under a project and all of their master page paths are determined like this:
MasterPageFile="~/zFrame/InterfaceMaster.master"
However when I run the project, I see the page giving following error:
The file '/interface/Intertech.Interface.InvoicePayments/zFrame/InterfaceMaster.master' does not exist.
Normally the master page must be in the "zFrame" directory. the second directory does not contain master page.
The whole site used to run perfectly until a few days ago. and only some of the pages come up with this error
