Board Thread:Support Requests - Getting Technical/@comment-188432-20130311202331

I know that once upon a time I stumbled across a "normal" view of a Thread page. That is, it looked like I'd accessed it without all the javascript and css "overlay". I need to do that again, because a user has totally screwed up a page by, apparently, not closing divs properly. Anyone know off the top of their heads how to get to the "backend" view of a Thread page so that I can edit the problem away?

The affected page is tardis:Thread:124276.
