We have had Server 2003 deployeed for over 2 years now without an issue. We have decided to install sharepoint simply as neat way to share documents so that the less computer savvy people know where to find them. This is a clean install with no customisations and their is no content on each page just the below error.
Web Part Error: A Web Part or Web Form Control on this Web Part Page cannot be displayed or imported because it is not registered on this site as safe.
Please see attached screenshots for details. I know nothing about sharepoint so I am a bit lost on how to fix this.
