[Zope-dev] nasty persistence problem

[Tim McLaughlin]

I seem to be in a bad spot.  When I restarted Zope after modifying some
products, I got a "Could not load oid.." for all URLs.

Basically, the only way I could even access anything was by doing an
"import Zope" in the Python interpreter and deleting acl_users which is
an instance of LoginManager.  And now I found out (once I was able to
login to ZMI) that two vital ZClasses are broken also.

So, I'm kinda stuck.  Here's the error:

Error Type: Could not load oid     ~, pickled data in traceback info    
may contain clues
Error Value: None

Here's the traceback if it helps...

Traceback (innermost last):
