Redmine

The JS error that happens is on calling this.toolbar (TypeError: this.toolbar is undefined
http://domain/javascripts/jstoolbar/jstoolbar.js?1348912828
Line 205).

jstoolbar is loaded.

How to bring back the toolbar online?

My environment:

Environment:
Redmine version 2.1.0.stable.10511
Ruby version 1.9.3 (x86_64-linux)
Rails version 3.2.8
Environment production
Database adapter Mysql2

Thanks!
