I've noticed for some time that after the redesign the tags stopped working properly (they weren't really working any better before though), and today I've forced myself to check it out. I've dumped UTW and now started to run simple tags and I've managed to run it for all tags (previously it only displayed categories as tags, and dumped empty pages for other tags added by UTW. But now I just couldn't make a tag cloud. I have some real life stuff to do now, but I think I can fix it in the evening. Sorry for all of the technical problems that we have been experiencing, I'm really frustrated about them!.
