Thanks you very much for responding to this.
I had a look at Configuration Manager / Registration Tab and the Show login on registration page = no.
If I unpublished the CB Login Module in Joomla Module Manager the bottom login in the syndicate footer disappears (Where I have CB login Module positioned.) Its the top login that is the question mark.
Also when I make changes to the CB login module it seems to reflect both logins i.e. showing / not showing icons. The problem is that I do not want the login positioned in the article area and want to keep it in the footer. So finding how and where to position and / or un-publish the second lo-gin is a pain. I've also unpublished and republished all I could see in the field /list and plugin management area. I may try re-install of CB and see it it makes a difference as well and uninstalling the Joomla Login Form module.
Also the original Joomla login form is unpublished and is/was positioned in the syndicate footer as well. Not sure why there is a login showing up in the article area.
