Checked. They were gone.

I think it using physical paths. In the error there are no traces of 
VHM. Although the site is doing with both Apache and Squid.

Well, after writing the post, I cleared every index and rebuild them. I 
didn't know I could Update it.

Clearing + Reindexing worked.

Somehow this "lost" object was affecting Plone's portal_factory: I could 
not create any new document of the folder that should have the lost object.

Thanks,
