I, too have the same problem. If I click on "full site" it just brings me back to the same page. There is not a "forum actions" setting, nor can I access the general settings. I only have the following options available:
Articles
Albums
Notifications
Forums
Profile (which only shows my profile - I can't change anything nor access the general settings)
Messages
Blogs
Friends
What's New?
I was going to post a picture of the page, but when I click on "Go Advanced" in the "reply to thread", it only brings up the quick-post, not the full advanced page, so I can't post pictures. Sorry!
