    text
    copied!<p>I have a static landing page (students/index.html.erb) that renders on my local server; however, when I push it to Heroku, the default public/index.html file renders instead of the landing page. When I delete public/index.html, public/500.html is served.</p> <p>I'm struggling to troubleshoot this issue. Hopefully, the below information helps explain my situation:</p> <p><strong>routes.rb:</strong></p> <pre><code>AlumniKickstarter::Application.routes.draw do resources :students # match '/', to: 'students#index' root :to =&gt; 'students#index' </code></pre> <p><strong>Gemfile:</strong></p> <pre><code>source 'https://rubygems.org' gem 'rails', '3.2.13' # Bundle edge Rails instead: # gem 'rails', :git =&gt; 'git://github.com/rails/rails.git' group :development do gem 'sqlite3', '1.3.5' end # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '~&gt; 3.2.3' gem 'coffee-rails', '~&gt; 3.2.1' # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer', :platforms =&gt; :ruby gem 'uglifier', '&gt;= 1.0.3' gem 'twitter-bootstrap-rails' gem 'libv8', '~&gt; 3.11.8' gem 'less-rails' gem 'therubyracer' end gem 'jquery-rails' group :production do gem 'pg', '0.12.2' end </code></pre> <p><strong>Output from running</strong> <code>git push heroku master</code>:</p> <pre><code>Counting objects: 5, done.
