Here, perhaps this may help you along... It was posted by another user previously, pertaining to 5.44a! I don't have any changes for forumdisplay.cgi however.. Perhaps do NOTHING in there, and see how it goes? (of course backing up your original files at ALL times in case something goes wrong). I loosely recall one of these hacks that I installed again recently didn't require anything done with forumdisplay.cgi afterall (with new versions).
