Sorry. I don’t know what this is, but all of the individual archives are broken. This may go on for some time — the last time I had to ask MT for support it took a week to get an answer. But I can’t get it working at all.
UPDATE: I did get a reply from MT support wthin eight hours, and on a Sunday. This is an improvement worth noting. By that time I had fixed the site — I hope — and have placed the instructions in a comment to this.
