Hi,
After adding 'live_support' to installed apps, got this error:

class Chat(models.Model):

File "d:\rank\rank_vir\lib\site-packages\live_support\models.py", line 33, in
Chat
support_group = models.ForeignKey(SupportGroup, null=True, blank=True)
TypeError: init() missing 1 required positional argument: 'on_delete'
