Hmm. I'd imagine Darth broke something during downtime yesterday ;P
Probably bad permissions on misc.php, since seems that everything feature that uses it (mark read, status update, etc.)
Unfortunately, I don't have access to it for security reasons so we'll have to wait til he gets back to figure out the problem.

But, things I noticed, for him to know where to look:

Code:

verification in admin panel doesnt show misc.php perms, so go in and check those first (seems like its missing execute permissions but honestly i cant be sure)

-- my base MyBB localhosted instance responds to misc.php w/ status 200 even though, yes, it doesnt actually return anything unless parameter specified
-- here, misc.php responds 500 to a parameter-less request ( http://makestation.net/misc.php )

-- go to bottom of page and click Forum Design in footer, since its a misc.php page. works. difference is, it's a GET req (req from ?page)
-- maybe open up misc.php and find where it does anything with ?action?
