When you install Microsoft Office SharePoint Server 2007 (MOSS 2007),
By Default the Contributor Settings will be enabled on your site(s).
You will notice this in the SharePoint Designer task pane.
This
is because your account is present in the Content Authors group, wich
may “restrict the use of some features” as the task pane mentions.This
behavior can be modified if you turn off the "Contributor Settings" in
SPD.
How to get this above window:
1. Open The site in SharePoint Designer
2. Site Menu
3.choose Contributor Settings.
4.Click on Disbale Contributor settings
5. Refresh the page and U will not see that message again !!!!
