So I just finished cleaning up the website, changing a few images here and there, disabling some plugins, then I had the great idea of upgrading WordPress and K2 to the latest versions.
Mistake.
The latest release of K2 is completely incompatible with my SmellyBroom.com theme. On top of that, I managed to wreck the entire database during the upgrade proccess. After a few hours messing with different installations, I gave up and imported all my posts and comments into a fresh install of WordPress.
I learnt something today.
If its not broken, make backups before fixing it.
