When a member wants to edit an entry on the EE control panel on a site we recently constructed, he gets these warnings (however, he is able to make adjustments):
1.

Severity: Notice
Message: Undefined variable: assigned_channels
Filename: cp/content_publish.php
Line Number: 2122
2.

Oddly, we copied this site from another EE site we constructed a few months earlier, but there are no PHP warnings there.
What have I done wrong, or did I forget to do?
