Hi,
have redownloaded & bug with calandar events is now fixed thanks.
Have run the query on my dbase for table moderation as requested:
Showing rows 0 - 0 (1 total, Query took 0.0002 sec)
so you're right there is one row there but vB shows 'no threads to moderate'. I've reported it on vbulletin.com although I know I could delete it manually but I wonder if there is a bug there.
