Specified folder not in Site Tree

Hi

We’re getting this error in the console.log file even though folder 783 is in the site tree:

PSSiteFolderAss    07/02/08 10:03: Specified folder, id=783, not in Site Tree 

It happens when we’re running the Site Root Incremental and Full content lists. We’re also getting this error when the publishing is in progress:

PSSiteFolderAss    07/02/08 10:14: SiteFolderAssembly:: a site id parameter is required, so a location was not generated

I’ve checked the content list and all items have a location and siteid. What else should I be looking for?

Rhythmyx 5.71

Cheers
James
