My site was giving this error on certain pages when I went into Edit mode then clicked Page and then Page Settings:

The solution was found here: http://stsadm.blogspot.com/2007/08/fix-publishing-pages-page-layout-url….

Download the STSADM extension for MOSS here: http://stsadm.blogspot.com/2007/08/fix-publishing-pages-page-layout-url….

Install it with this code: stsadm -o deploysolution -local -allowgacdeployment -name Lapointe.SharePoint.STSADM.Commands.wsp

To run the command on the whole site:
stsadm –o gl-fixpublishingpagespagelayouturl –url “http://eastpak/” -scope webapplication

To run it on a page:
stsadm –o gl-fixpublishingpagespagelayouturl –url “http://eastpak/students/teststudent25/” -scope page –pagename targetedportfolio.aspx

At any time, you can add –test to the command to see what it will be changing.

NOTE: It will not work on pages that are checked out.

Thanks to Gary Lapointe for the program.
