WRoom EA : error in console when (404 caused by the toolbar)

Just after an installation and a first site creation (which has failed using the import) I create manually (no import) a new site using web-templates

I create a page using the Simple Template, the page is created and I can access it in Edit Mode nevertheless I've got an error in my console on each acess, and I have the same problem
. I still can use my build, but we can't launch with such an error trace on each page request

2009-03-11 04:00:47,624: ERROR [org.jahia.services.sites.JahiaSite] - Cannot find home page, -1
org.jahia.exceptions.JahiaPageNotFoundException: User message=404 Not found - Page:-1, System message=404 error - page [-1] could
not be found in the database or is no longer accessible.
