I’m having the same issue, with the same results as Fabbio. Renaming the cache.php gives me an error, but renaming it back gives me the blank blog again. I can’t load my wp-login page. Tried to upgrade to the latest version of WP, but the upgrade.php page won’t load, either. Everything is just plain BLANK.

Other subsections of my site work fine (http://jenba.net/gnomesby and http://jenba.net/simscribes) so I’m not sure what the problem is. I can access the site via FTP just fine.
Before I attempted the WP upgrade, I hadn’t touched any files in that folder for months. So I hadn’t made any recent changes. Anyone have any ideas?? I’m at a loss.
