I've been working on customizing WordPress for a site that I'm building, but I've run into a bit of a weird issue with the right sidebar. It took me a few moments to find out how the system generates the sidebar, but with some finesse and elbow grease, I was able to get the parts of it appearing how I want (with graphical headers). I've now run into a very strange issue though.
It seems that on the main page of the blog and even on categorically or tag-filtered views, the sidebar has the tag cloud, category list, recent posts, and recent comments. However, when I'm on a full post (single post) view, the tag cloud is empty, categories says "no categories", recent comments is empty, and recent posts is completely missing.
Does anyone have any thoughts on how I can fix this?
