  helpers Toadhopper
end
```

Fix so it works with Sinatra::Base and classic Sinatra
user
```ruby
require 'sinatra/base'
require 'toadhopper'

module Sinatra
  # The Toadhopper helper methods
  module Toadhopper
    VERSION = "1.0.2"

    def self.registered(app)
      app.helpers Toadhopper
    end

    # Reports the current sinatra error to Hoptoad
    def post_error_to_hoptoad!
      unless options.toadhopper && options.toadhopper[:api_key]
        STDERR.puts "Toadhopper api key not set, e.g. set :toadhopper, :api_key => 'my api key'"
        return
      end
      filters = options.toadhopper.delete(:filters)
      toadhopper = ::Toadhopper.new(options.toadhopper.delete(:api_key), options.toadhopper)
      toadhopper.filters = filters if filters
      toadhopper.post!(
        env['sinatra.error'],
        {
          :url => request.url,
          :params => request.params,

        },
        {'X-Hoptoad-Client-Name' => notifier_name}
