  2. Created a new admin
  3. Changed admin user values to something else and back
  4. Changed to default template
  5. Disabled ALL plug-ins
  6. Re-installed latest version

What would you do next?

I had some problems upgrading to 3.0.3 on a multi-site installation. I had used the automatic upgrade and it failed, but luckily, downloading and extracting the new files from WP.org and uploading them directly fixed it. I would try that first. If that doesn’t work, try re-uploading your backup files. You did make a backup, right?
