@simon I just tested with my admin. Even if I log out using the admin bar link, it doesn’t seem to log out of the forum.
Interesting idea. Here are what my rules settings are: http://share.ptlrdsgn.com/2x08092G1T1K. Because the site is private, I am protecting all pages except the few that I exclude. Is there a specific page I should exclude that could be causing issues with the Discourse login integration?
