Today I upgraded all of the modules to the most recent versions. I've been lax. Sixteen were in need of update. Tomorrow I'll upgrade the Drupal core to the latest version. First I've got to track down where I made changes to the caching headers so I can recreate them. It's annoying, but a necessary evil. And as unfriendly as it is, I think it's a good design choice on Drupal's part.
