Sounds like the auto_increment for the post_id got messed up? Can you look at the table in phpMyAdmin and see what the next auto_increment will be? Maybe you can reset it so there’s no conflict? I’ve never heard of this before, so I am just thinking about what I would do if it happened to me.

I have heard of key problems like that after upgrading versions, but you say yours has been OK for a couple months, so it’s not likely to be related to that.
