Going back to admin party

# is not a valid comment in this configuration format, Use ; instead.

If you try to login as #admin (rather than just admin) it will let you, if you give the right password. So, either remove the line altogether, or prefix it with ;.

You can also do that through CouchDB Web UI.

1. Go to the configuration panel (http://127.0.0.1:5984/_utils/config.html in CouchDB 1.x or http://127.0.0.1:5984/_utils/#_config in CouchDB 2.x).
2. In the admin section, delete all rows.
3. Relax: this is "admin party" again.
