This error is occur on that time when u have declared a variable name and the control name same as variable name. When you run your application on local system there is no error occurred but when you uploaded your web application on server you got this error. So I would like to suggest you that always make sure that your control name and declared variable is not same

For example:

asp:TextBox runat=”server”

and in the code behind file you might have

private Int32 userID = 0;

2. Check the Log me on automatically each visit  (check box)

3. Now go to http://yourdomain.com/adm and enter password only

4. Now you can successfully entered Administration Control Panel already.
