Greenie forwarded the post that you had done which had the typographic quotes. Also, Cleo had a problem with the typographic ... being entered.
I've filed a bug report with Vbulletin, they've given me a list of things to try which I will do later at night when there are fewer people on the board. The problem appears related to the newer version of php which must treat those characters differently. The differences in php 5.1 and php 5.2 really shouldn't have made a difference as far as I can see, however....
