It appears as though something went askew when I upgraded to the latest version of MT. Not sure what happened as the upgrade did complete successfully however the themes didn't look like it came across.
I can sit down and try and fix it, but I'm going to take this opportunity to go through this weblog and clean things up a little. First cab off the rank is to clear up the markup and style. So for a while, to those visiting the site in a browser, you'll see the site "naked" with most of the styles removed.
