Unfortunately it appears that you
have modified your database directly, so there are all sorts of issues that can arise from doing advanced actions directly on the MySQL tables.
You'll need to restore from the backup you created (you should always create a backup before any changes, and it was stressed in the other thread
here), or you'll have to accept that your posts are all HTML now and update the database to not parse bbcode in those posts and set your edit post timers to not allow editing posts prior to your MySQL adventure this morning.
Again, I cannot stress the importance of creating a backup before ever making database adjustments.
