Cannot login in RabbitMQ Management web console

I have installed RabbitMQ Server installed in CentOS 6.6 and I have also installed and enabled Management plugin. If I run the command rabbitmq-plugins list this is what I get at console:

I'm trying to access with guest default user after change it password through rabbitmqctl change_password guest <newpassword> but any time I try to login at http://localhost:15672/ I got Login failed message. I have check guest permissions and apparently are right ones:

rabbitmqctl list_user_permissions guest
Listing permissions for user "guest" ...
/       .*      .*      .*

So, what I'm missing here? Why I cannot login into Management console?

Guest login is deactivated in production environment.

So you must create a new user.Also i think, it is a good practice to delete guest user in production environment after create a new user.So

sudo rabbitmqctl add_user myuser mypass
sudo rabbitmqctl set_permissions -p / myuser ".*" ".*" ".*"
sudo rabbitmqctl set_user_tags myuser administrator
