"Error Illegal characters in input (potential scripting attack)"
What is going on? I've tried using different wysiwyg and no wysiwyg with the same results. It doesn't happen in any other HTML field I can find in CiviCRM or Drupal, only when creating a new mail message but I can't save or send a message because every attempt causes the script to be added and the error to be triggered.
HELP!! This wasn't happening before the upgrade. But I'm stumped for a cause.
