It took me (as a Zope newbie) quite a bit of time to get zForum working in my
non-standard setup. The causes were twofold:
1) Incorrect CookieCrumbler import when using the one from CMFCore (instead of
standalone)
2) zForum doesn't reckon with non-default 'Products' directories (these can be
set by the 'products' variable in zope.conf -- as it happens in my case).
I've send an updated version to zForum developer Julian Flores
(jflores at codeit.com). I expect a new version will come out some time.
