I am using the current version of WP multi-site (I read up and understand the fix for the icons, but haven't implemented yet) and am having an issue with the individual post pages, as well as if you click on a tag. When you try to view either a single post or a tag search page, you get a blank screen. If you refresh, it loads fine.
This does not occur when viewing a page or a category search page- those load perfectly the first time.
I've tried this in a couple of different browsers with the same result.
