...all my pages!! How to solve it? I am learning share point 2007 services and technologies from few weeks. I am working on some default pages. For this I am using share point designer 2007. But I can not see my default.aspx page in the Design view!!!. It shows only errors for the controls I am using. I can see this page in code view with red underline under the related controls. This page shows properly in IE.
In the design view all the errors have red text like "Error Creating Control -" and gray rectangular background in place of that control.
Here is one of the error :
Error Creating Control - SharePoint:delegatecontrol
Unknown server tag 'SharePoint

elegate Control".
Please help me to solve these kind of errors and view my default.aspx in the design view properly.
Actaully I can not see any page properly in the design view becuase all the pages have this kind of errors "Error Creating Control".
