HUMMINGBIRD AFFECT THE APPEARANCE MY WEBSITE

Hello,
I just activated the Hummingbird plugin and tryed to optimize and minify the css and javascripts from my website, after the process is finished my website turns in blank, but not all, only container, the footer style I realized that is the same, when i check the source of my website after clearing the website cache with w3, the css, js is the same,on header and footer, but is not minified, is pretty weird this.
Can anyone help me, or to login into my wp to solve it? please!?

Kind of regards.
