No works with some themes

I have been using in a web with Tweenty Seventeen theme and it works like a charm but when I tried using it on Go Theme it breaks all my css and they are not loaded on the page.

I really liked this plugin but until this is not solved I will have to unistall. Please solve it and I will install it again.

P.S: I have seen that it only breaks the css when you are logout. If you are logged in WordPress, the css are loaded and the page is displayed as it have to do.

Thank you!
