You you make extensive use of PostgreSQL, e.g. in your top level
UserFolder?

Then a problem to successfully loads the "DA" module may be at the
root of your problem.

That looks quite bad:

     For unknown reasons, the "_storage" saved in the
     ZODB connection is "None".

Apparently, something went seriously wrong during initialization.

  I had similar problems (though not that drastic ones)
  when I upgraded my Linux system and the (implicitly) newly installed
  LDAP libraries (used for LDAPUserFolder) did no longer work
  with my installed "python-ldap".

If necessary, I would see what happens in an interaction Python
interpreter:

	python:
	  from Zope import app
	  R= app()

You will need to extend your "PYTHONPATH" to include "<zopedir>/lib/python".
Hopefully, you will get a good problem description.
If not, you will need to debug the "app()".
