Okay, first a good advise... don't use ifconfig anymore, it doesn't
tell you the whole truth. It has been deprecated since they introduced
IPv6 and Netlink to Linux.

use "ip addr" and "ip link" to get a better look what is going on in
your system.

Could it be that you removed the 127.0.0.1 address from your loopback
device? Adding a second address for the "OLSRv2 routable address" is
good, but removing the 127.0.0.1 will get you all kind of trouble.

There is no interface anymore on your system with the IP 127.0.0.1 to
bind the HTTP plugin port.

There is no interface anymore on your system with the IP 127.0.0.1 to
bind the Telnet plugin port.

I hope this helps.
