Hello,

I am reading chapter 4 of the book and attempting to make a very basic change to a copy of the v4.master file. Everything appears to be working, my change appears the design view within SPD. However, when I save, check in and approve the masterpage upon loading my site I recieve this error:

Error
''<asp:Literal' is not a valid virtual path.
Troubleshoot issues with Microsoft SharePoint Foundation.
Correlation ID: 4c4866cc-13b2-4a1c-aa06-e0a4bd547b32
Date and Time: 2/5/2013 12:42:32 PM

Any assistance would be greatly appreciated!

Thank you.

You have an ASP control in your custom master page that SharePoint Designer is butchering. It's monkeying with the ASP syntax. Re-paste your control code; you'll need to do this every time you open the master page in SharePoint Designer. Alternatively, download the master page via the browser and edit it in a text editor.
