Please refer to my previous post. The images don't show each plugin's version, so it won't help to troubleshoot in this way.
Like I said previously, it may not be a CB plugin that's causing the problem. This can be caused from another component, module or Joomla plugin that is not 1.5 native.
It's always good to periodically check for the newest extensions to keep your site up-to-date and secure, so your best bet is to just go through each one, update if possible or simply uninstall old ones. If it's a plugin or module, sometimes just disabling will help you find the culprit, but other times, uninstalling is the only way to find out.
You can also try the opposite method (and probably the best). Start clean with a new install of Joomla and CB (after backup of database and site of course) and then add only the extensions you need, making sure to check for 1.5 native-compatibility on each.
