I tried to remoived <%= render_main_menu(@project) %> in base.html.erb.

Project page now work, but project menu on page (New task, etc.) - no... 
Environment:

Very Good, I have the same problem migrating Redmine 0.9 to 2.0, but i use

UPDATE `projects` SET `parent_id` = NULL WHERE 'parent_id' =0;

on my MySQL.

When I list the next tables

SELECT id, parent_id, lft, rgt FROM projects;

I see "NULL" on parent_id table.

It Works.
