I have earlier proposed an RSS functionality from the CB Blog component. Quickly and promptly I got a good answer.
Following this answer, I re-configured the CB Blog plug-in, changing the Model to "Joomla". I put Mode to "Intro and full" which gives me two edit boxes later.
However, this doesn't work. When trying to add a blog entry in the front end, the front-end tells me I have not cookies enabled/session expired.
However, the other two settings, "Intro only", or "Full only" both work (!)
Have I missed something?
