Redmine

After upgrading from 3.4.6 to 4.0.0, redmine refused to launch.

The culprit was render_parent 0.0.8 using alias_method_chain which is not supported in rails5.

$ rails --version
Rails 5.2.2

I edited

/var/lib/gems/2.5.0/gems/render_parent-0.0.8/lib/render_parent/rails3/on_load_action_view.rb

and uncommented all lines with alias_method_chain assuming after which redmine came up.

Relevant nginx log:
