Critical crash of Futon after misconfigured bind_address

Bug1: Unable to reflect bind_address in local.ini
Bug2: Unable to revert changes doing clean install
Bug3: Can only change bind_address in Futon

I made a mistake to change the configuration table's httpd/bind_address parameter to my domain, the domain that looks like www.google.com etc. That was supposed to be left at 0.0.0.0 or 127.0.0.1. I remember making this mistake long time ago but now basically I can't access anything from either localhost and external.

Please check screenshot to see what it looks like when I try to access Futon after misconfiguration.

I am unable to reverse my setting because working with /etc/couchdb/default.ini or local.ini never affected this in the first place (spent 2 hours trying to modify these fails in order to get external access of couchDB).

So Futon must have changed something when I set it. When I change the value, it stuck at the error: Some of the changes require database restart. Since then, I can never access my couchDB.

I tried to yum remove erlang, yum remove couchdb several times. Checked to see if any default.ini or local.ini remains, restart system, log out users, but none of above works.

Please help me with this problem as soon as possible.
