Redmine doesn' start - Object is not missing constant Issue - redmine

After trying to install a new plugin (already uninstalled), my redmine application doesn't start and I really can't find what happened.
Here goes the backtrace:
*** Exception ArgumentError in PhusionPassenger::Railz::ApplicationSpawner (Object is not missing constant Issue!) (process 834):

Rails giving undefined method `workers' for main:Object (NoMethodError)

I am trying to setup puma on heroku for a rails app. I'm following Heroku's guide on how to do it, but the config file they give doesn't seem to work, and I can't figure out why. When I don't use any config file, it runs fine, but I want to be able to specify the number of workers and threads it uses.
When I try to run the server, I get the following error:
C:/Users/Ephraim/Documents/lis/rails_app/config/initializers/puma.rb:1:in `<top (required)>': undefined method `workers' for main:Object (NoMethodError)

Here is the puma.rb initializer I'm using:
workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count
preload_app!
rackup DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
on_worker_boot do
# Worker specific setup for Rails 4.1+
# See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
ActiveRecord::Base.establish_connection
end
What would cause this to happen? And how can I fix it?
Referencing an answer from here: puma initializer does not work with rails 4.2
Put the puma.rb file in config/ not config/initializers/
you need to use foreman https://github.com/ddollar/foreman to run the Procfile. That is how heroku will spool up the app. once installed foreman start should do the trick. this just fooled me for a bit and I ran across your question.
