Please Friends!!!

I have tried to do this:

sudo su openerp

cd /opt/openerp/v7/server/

./openerp-server -c /etc/openerp-server.conf &

Here is my openerp_server.conf:

[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = False
db_port = False
db_user = ubuntu
db_password = False
addons_path = /opt/openerp/v7/addons, /opt/openerp/v7/addons/web/addons, /opt/openerp/v7/addons/web/web_kanban

I got this error:  NO HANDLER FOUND.

and this:

Maybe you forgot to add those addons in your addons_path configuration.
