login and logout errors - Joomla! Forum - community, help and support

if users comes site , uses login , logout module comes joomla, works fine. however, if users tries login , logout via ccboards, there errors.

if user attempts login via ccboard, receive "invalid token" message

if user attempts logout via ccboard, redirected page on site says "you logged in private area of site." , there logout button. if use button logout receive a:

error 404 - not found
your browser can't find document corresponding url typed in.

message , url looks like:

http://funkyhousebeats.com/%fe)%dd%7b%1aa%a6%8am%8a%89

1) there way can remove login link , logout link ccboard?
2) there way can make login , logout functions of ccboard work joomla?

i've looked on , can't find how rectify error.
