Our upgrade problem with Zope 2.3.0 in fact was because of the Product LocalFS. After we deleted the single LocalFS object from the old Zope tree in 2.2.5, we could copy the data files to 2.3.0 and continue working without any problem. Interesting point: Before we deleted LocalFS (yesterday) we had a problem in EVERY subdirectory with SiteRoot (we had to manually delete the SiteRoots in 2.2.5 and then add them in 2.3.0). Now today, after we deleted a LocalFS object in 1 single subdirectory (and domain) the SiteRoot problem didn't appear in any domain (out of 10). Is this only a Fata Morgana or what? I cannot imagine, that a single LocalFS object in a subdirectory creates a SiteRoot problem in every concurrent subdirectory. Whatever. Thanks to everybody who pointed to LocalFS. -goe- _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
