Did you also clear the extra data out of the user_meta table?

So far so good.

That suggests to me that you have some problem that is unrelated to  
this plugin.  Nothing I know of in this plugin should prevent you  
from logging out.

Deactivate the plugin in both blogs, and see if the logout problem is  
still there.

Actually, first just clear your cache and see what happens. :)

I suspected this might be the case.  I emailed the plugin author  
separately asking just this a few minutes ago.  Is the login/password  
the same or different on the two databases?

WAIT! I've got it!  The two have to have different prefixes.  Right  
now they both think they are the master blog.  This is a bug.

(Though I'm still quite sure the "can't logout" problem is something  
unrelated to this plugin.)

Hey Curt -- if you're reading this, my "auto detect Master/Slave"  
suggestion just hit a snag!  :0  Maybe test for both prefix _and_  
database name?
