ApplicationHelper::ThemeChangerUserSetting is uninitialized

[shaoran]

I've installed the version 0.4.0 (from the releases page).

I'm running with ruby-2.6.5 & redmine 4.0.5 and after executing bundle exec rake redmine:plugins:migrate RAILS_ENV=production I restarted the ruby proc. I get this error

How can I fix that?

Is this still a problem? Is this reproducible on Redmine 4.1?

I don't know. Because I had this issues, I removed this plugin when I upgraded to redmine 4. I will have to test it with version 4.1, so I will need to make a copy of my production env and test it there. I'll do that in the weekend and let you know. Thanks.
