Now and then, when viewing my WordPress.com blog all the style elements disappear so that the blog looks like a sitemap. I am working on a Mac. This happens in Firefox, Safari and Rockmelt. I have tested this on other computers, but it only happens on my one computer. The problem goes away when I clear cache, but it will return randomly. This also happens, occasionally, when viewing other WordPress.com blogs. The problem has been going on for about a month.
The blog I need help with is fitzmahan.wordpress.com.
