I have found a fix that works for me. I downloaded a fresh copy of WordPress to my computer and via FTP, replaced just the wp-includes and the wp-admin folders. I found this fix as the answer to a related forum question, but I failed to copy the link to that page. If I can find it again I’ll post to this page.
I have this exact same issue. My site was auto updated via Dreamhost and I’m not running any DB Cache plugins. I’ve actually deleted all plugins and renamed my themes folder so that it’s pointing to twentyeleven. I have another site with the same host/on the same server (but using twentyten), but I believe I somehow updated that one manually before the Dreamhost auto-update happened (if that’s even how it works).
I’m very new at this and hoping for a solution other than deleting the entire site and doing a fresh install of WP.
–thank you
