With WP 3.6.1 and the last stable version of this plugin I have a whitespace (looks like a tab) before
this messes up some scripts and triggers a console error
I disabled all my plugins and figured out the problem was when this plugin was activated.
I was unable to track where the error was from plugin files. I tried to remove all php closing tags
?> but that didn't fix it
It might be inside the minify engine or something outputs the page, maybe a whitespace somewhere
