Invalid route name, already in use: 'review_worklog'

[it8090]

redmine 3.2.1 install worklogs :

An error occurred while loading the routes definition of worklogs plugin /apps/redmine/htdocs/plugins/worklogs/config/routes.rb): Invalid route name, already in use: 'review_worklog'

You may have defined two routes with the same name using the :as option, or you may be overriding a route already defined by a resource with the same naming.

For the latter, you can restrict the routes created with resources as explained here:
