running openerp 6.1-1 - missing openerp-web project

I am currently running OpenERP 6.1-1 on ubuntu.

Prior to this there was no error but since Feb 2nd 2014. I got a "No handler found." message.

My openerp-server.log have this message:

The `web` module is provided by the addons found in the `openerp-web` project.
Maybe you forgot to add those addons in your addons_path configuration.

=======================================================================

Have not found a solution after googling on the internet that works for me.

And, my current installation does not have "openerp-web" module in the addons.
My installation only have this directory:

addons/web

Please help....

Thank you.
