I've got Wordpress SEO 1.4.6.
Regardless of the well known problem with SEO and Simple press Forum page titles being all the same, My forum shows up on top, and then once again embedded within my wordpress template as it should. As soon as I deactivate the plugin, the page looks normal, and forum shows up only within the page. This only happens on forum page, all other pages work normal.
It doesn't matter if I'm logged in the WP dashboard or not.
