Almost went crazy when I realised that comments couldn’t seem to be posted properly on this blog shortly after upgrading to WordPress 220.127.116.11. After a little swearing and 2 almost-clean installs of WordPress (everything fresh except the MySQL database itself), I was just about to consider the possibility that perhaps it was time to start the blog anew (on hindsight, I’m not sure why I even considered this – I must have used and reinstalled Windows far too many times!) when I googled upon this really helpful blog entry. Turns out that a “blank” user was somehow created during the upgrade procedure; deleted it, and now comments work properly again. Phew!
