My core Drupal modules are in the filesystem, yet they don't appear in the modules list. In fact, they even appear to be deactivated as contrib modules that depend on the core modules aren't working now.
I can think of no change to my system except that I installed Form Store and Javascript Tools and enabled AJAX Submit.
After I noticed these problems, I upgraded to Drupal 5.5 and ran the upgrade script. This did not fix the problem.
Any ideas?
