Weird Active Admin (Rails) error

Question

This is by far one of the most absurd error's I have come across. I log into active admin and get this on my screen for any active admin page:

(?i-mx:</body>)

I checked out the server logs, and I seem to be logging in successfully, and the server calculates the queries for all the columns but the final output is the above! I am using ruby 1.9.3, rails 3.1.3 with active admin version 0.4.4.

This following is a sample log output for one of the page loads:

I found a cleaner way to handle this by looking at the mini-profiler docs and reviewing the available config options in the config class

in a config/initializers/mini_profiler.rb

Rack::MiniProfiler.config.skip_paths << '/admin' #or whatever you namespace active_admin under

side note, there are a couple other useful config settings:

Rack::MiniProfiler.config.use_existing_jquery = true
Rack::MiniProfiler.config.pre_authorize_cb = lambda {|env| Rails.env.development?}
