Error when opening configuration page on Redmine 3.3

[danielvijge]

When opening the configuration page (either a new config, or an existing config) there is an internal 500 error. This error is related to a specific commit on Redmine: redmine/redmine@223141a When rolling back this commit, the configuration page is working again.

The error in the log is:

ActionView::Template::Error (undefined method 'humanize' for nil:NilClass):
    12:         <p><%= f.select :flg_active, [['True', 'true'], ['False', 'false']],

I use Redmine version 3.3.1
When adding a new configuration, I see the error
Redmine. Error 500
