Dear all, I was encountered with a login in issue . I've changed domain name and display name to IP , but when I relogin now, I can't reach login page , and it reports as below :

500 Internal Server ErrorSite matching query does not exist.

Oops, something has gone wrong!

And I set 'DEBUG = True' in settings.conf , and it reported like below :

DoesNotExist at /accounts/login/ Site matching query does not exist. | Request Method: | GET | | Request URL: | http://127.0.0.1:8000/accounts/login/?next=/scheduler/job/42 | | Django Version: | 1.11.14 | | Exception Type: | DoesNotExist | | Exception Value: | Site matching query does not exist. | | Exception Location: | /usr/lib/python3/dist-packages/django/db/models/query.py in get, line 380 | | Python Executable: | /usr/bin/python3 | | Python Version: | 3.5.3 | | Python Path: | ['/', '/usr/bin', '/usr/lib/python35.zip', '/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/usr/lib/python3.5/lib-dynload', '/usr/local/lib/python3.5/dist-packages', '/usr/local/lib/python3.5/dist-packages/icsectl-0.2-py3.5.egg', '/usr/lib/python3/dist-packages'] |

So I just wanna know how can I set it back?

Yours , sincerely

Su Chuan
