Boilerroom Breaks 1.21.1 Site wide
I appended this information to boilerrrom's discussion page, but thought I would put it here also.
I use Boilerroom, createBox and Input box regularly. After upgrading to MW-1.21.1 Inputbox and CreateBox both ceased working. I dissabled all extensions, and manually created a link to non existant page with preload=Template"something/something (which did exist). While all extensions were off this worked fine.
I than activated one extension at a time ( so only was active at any given time), flushed the various caches, and tried the link again. When I had activated Boilerroom, the link no longer worked. At no other test did the link fail.
Just thought I would give you a heads up (and request a quick fix since I need all three of the extensions) ;-)
