Hi there,
Can you post the relevant code for the MasterPage and the BasePage class? E.g. the full Code Behind of the master page, the page directive of the master (from Markup View the line that starts with <% @Page) and the full code for the BasePage.cs or.
vb file?
Please use the code button on the toolbar when replying to make the code easy to read.
And what do you mean with "it shown DarkGrey eventhough Monochrome theme as well"? What is shown where?
Finally are you sure your browser is setup to allow cookies? You can view Cookies with IE's Developer Toolbar. Part of IE 8 through the tools menu or available as a separate download for older versions
Cheers,
Imar
