By internal model I meant within CB Blogs > Parameters > Blog change the Model parameter to Internal. I've retested both Joomla and Internal models as working. So my best guess is the menu item being used as the forms URL is likely what's causing this.
I also noticed that the comment function for posts doesn't work; nothing happens at all.
Ok, then this is absolutely a menu item issue. CB isn't properly reachable. Go through your menu items linking to CB and switch them to Public access 1 by 1 to find which is doing it unless you're comfortable using your browsers developer tools (press F12) to view the network tab to see what URL it's trying to submit to when you comment.
