Hello,

I have an issue with the checklist-plugin .
Dimitar (Support) sended me a new plugin version redmine_checklist-210521-m.zip.

I have installed your plugins (download below) with the effect that redmine crashed completly.

Message from application: Missing helper file helpers/checklists_helper.rb (AbstractController::Helpers::MissingHelperError)

I think this was an installation issue in file checklists_helper.rb:
