Hello,
I'm getting this message, as it was advised in the manual to create public menu items, so I did, please see screen attached, but still getting the error message.
In order for CB to function properly a Joomla menu item must be present. This menu item must also be published for PUBLIC access. It appears that this environment is missing this mandatory menu item. Please refer to the section titled "Adding the CB Profile" of the PDF installation guide included in your CB distribution package for additional information regarding this matter.
