The error may well be the one below, or it may be something different.

'NoneType' object is not callable

Their may be more than one tool causing the issue (bbmenus, bbwebsite)To remove all references:

ZMI > portal_controlpanel the reference to the tool(s),

also the type maybe reference in 'types_not_searched', 'default_page_types',  'typesUseViewActionInListings' etc

ZMI > portal_properties > site properties >  

Remove from Tool Registry

To delete it from the deep level tool registry. This worked for me with portal_bbclickcounterin Networks on dev. To do this you must:

Back up your instance

Shut it down

 ./bin/plonectl stop
 ./bin/instance debug

or zeo..

 sudo bin/shutdowncluster
 sudo bin/zeoserver start
 sudo bin/client1 debug

or just

 sudo bin/client1 stop
 sudo bin/client1 debug

then at the python >>> prompt

setup_tool = app.myportal.portal_setup      #myportal = portal id
toolset = setup_tool.getToolsetRegistry()

If you've forgotten the name of the tool, you need to check using:

for item in toolset._required.keys():
    print item

This prints out a list of everything contained within this record. Once you have the name of the tool required, in this case portal_bbclickcounter, do the following

if 'portal_bbclickcounter' in toolset._required.keys():
    del toolset._required['portal_bbclickcounter']
    setup_tool._toolset_registry = toolset

from transaction import commit
commit()
app._p_jar.sync()
