I have the front-end user login plugin running to protect pages from public. When I create a page named guestbook with introduction text and {guestbook} and protect it, only the introdution is hidden. The guestbook is still visible without login. How can I sove this?
I tried to put the {guestbook} into a component, but could not find out how to do it.
Thanks for your help!
