Is 'Localizer' a normal Folder, or an instance of some Folderish Product? Your setup looks correct, so that's all I can think of.
Localizer is the language selecting stuff, not a normal folder. But going for your version thing solved the problem ! I grepped _vh_ in the SiteAccess product and it found nothing. Checking out zope.org I noticed that there was a 2.6b1 out there. Downloaded that and lo and behold: The SiteAccess now had a test against _vh_. Moved over only that Product to my site as I am not sure how to upgrade without loosing my scurrent work. Restarted Zope and it worked !!! Seems like the 2.6a1 version for some reason dropper the _vh_ stuff.... It is there in the docs though. Anyway thankyou a lot for giving me someone to talkto about this, it helped a lot.
