[Zope] SiteRoot in Zope 2.4.0

Hello all, I installed the new version of zope and I set it up using various SiteRoot objects. Everything seems to be working correctly except that the "Folder at /email/OLD" link does not seem to work. It does not follow the base set up in the SiteRoot object. Furthermore, (this is not important but might be related) the link to the style sheet that the management screen uses can not be found. Does anyone know if there is a fix to this? Thanks
