When you select the person-dropdown and others in upper right to right of Search, nothing happens. You expect to see your name, update profile, and admin, but the dropdown doesn't drop down.

This is because a flag defer_js is set.

To undo this:

• You can put the following line in /conf/local.php:
  $conf[“defer_js”] = true;
• Or you can try going to
  /doku.php?do=admin&page=config
  directly to make the change.
  For here it would be
  https://wiki.toku.us/doku.php?do=admin&page=config

On the config page, the setting is in Feature Flags, after Advanced and before Network
