I have upgraded to Opera 10.52 today, so it can be a source of the problem, but who knows. When I click on the "newest post" triangle (left to the thread topic on the subforum view) I am not taken to the newest post, but every time to the same post. It doesn't happen in all threads, but for example in "HB Evo thread" triangle always links to https://www.physicsforums.com/showthread.php?goto=newpost&t=399702 [Broken] and I am always redirected to https://www.physicsforums.com/showthread.php?p=2696256#post2696256 [Broken]. Could be that happens in the threads I have posted in today. Unfortunately, evening seems to be slow on forums so I can't check details.
