I keep getting this warning when I update a view in a panel (I used the Views and Panel modules to create a custom home-page design). We are building an intranet for our company and our IT department has linked our SharePoint network credentials to the Drupal site using LDAP (if this would explain the warning at all). Below is a screenshot, please advise!

The accepted answer is outdated — see the hilariously-frustrated response by dddave to the users who keep trying to apply a patch that’s already been committed.

The updated answer is to download the latest -dev version of CTools, which has the proper patch already rolled into it.
