I was trying to tweak my comments code, and now seem to have managed to make the text of the actual posts disappear if you try to view them on a single page. You can still see the comments, but no post text, which is a real pain for the posts people have linked to directly.
I’m sure I will eventually work this out, but in the meantime bear with me.
Update: sorted. Deleted something I didn’t mean to delete.
Of course, now I’ve lost gravatars again and rude Emma from the single-page sidebar, but I’ll get them back up tomorrow. Fixed now.
