If you’d visited my site recently, you’d see I’d been playing around with the Presswork theme. Unfortunately, when WordPress upgraded to 3.3, Presswork became incompatible; if you haven’t upgraded from WordPress 3.2, stay there. Update: Presswork has released version 1.04 to WordPress and a release candidate to anyone brave enough to use it; I have it here.
If you have upgraded, you’re okay as long as you don’t change anything. I didn’t have any problems until I tried to drop one sidebar. Presswork is notable because of a slick overlay it uses to help you layout your site in context. You add and remove components while looking at the front page. I activated the drag-and-drop tool and deleted my second sidebar. After that, all of the headers disappeared. I reset the entire theme (which was another great reason to have my CSS in a custom file, separate from Presswork) and the headers came back. As soon as I tried to configure, though, or move an element, I lost all the headers. At one point, I lost all of the elements, including the content!
I still like Presswork and will keep an eye on when it is upgraded and probably reimplement then. For now, I’m using this as an opportunity to play around with other themes.
