I’m not sure I understand what’s happening here..
In Sutrayana, you have the root breadcrumb as ‘Discussion Forum’.. I can see that page in your WP page lists – Although it’s the only page published by the user with the login details you supplied us, the others all published by a different user. Strangely ‘Discussion Forum’ doesn’t show up in the list of options in Forum > Integration > Page and Permalink and instead the page ‘Forum’ is used which I can’t find in the WP pages list.
In Touching Enlightenment where you have the problem.. I can see no mention of the page ‘Discussion Forum’ anywhere in the WP pages list. The page ‘Forum’ is there and is also the page used in Forum > Integration > Page and Permalink.
Is there something I’m missing due to multisite? I admit I have no experience with multisite’s, but it’s the only thing I can think of especially due to Touching Enlightenment using a page title I can only find on Sutrayana.
My advice would be to create a ‘Discussion Forum’ page on each site individually, and try reapplying the forum page to the newly created ‘Discussion Forum’ page in Page and Permalink. Make sure you then update forum permalink and update the panel at the bottom.
