Title: Optimizing css breaks site (another one) Last modified: November 1, 2016 --- # Optimizing css breaks site (another one) * Resolved [lwkooy](https://wordpress.org/support/users/lwkooy/) * (@lwkooy) * [9 years, 6 months ago](https://wordpress.org/support/topic/optimizing-css-breaks-site-another-one/) * Hey, * First: love the plugin, Great job. * Question: I tried enabling the ‘optimize css code’ several times, excluding several things (e.g. what was suggested in [https://wordpress.org/support/topic/autoptimize-optimize-css-code-breaking/](https://wordpress.org/support/topic/autoptimize-optimize-css-code-breaking/)), but I can’t get it to work. * Whenever I enable the optimize css code function, it pretty much throws away my entire css. * The result (with css optimization enabled) : [https://www.webpagetest.org/result/161101_J6_P15/](https://www.webpagetest.org/result/161101_J6_P15/) but the screenshot actually looks like this : [https://ohiobear.com/wp-content/uploads/2016/11/Capture.png](https://ohiobear.com/wp-content/uploads/2016/11/Capture.png) * Dank :).

A bit of the ‘more is more’ philosophy :). * Of course! I disabled all the minify and combining funcitons of wpfc (only ones left checked are ‘Cache System, Preload, Gzip and Browser Caching). * thanks!! * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 6 months ago](https://wordpress.org/support/topic/optimizing-css-breaks-site-another-one/#post-8381482) * ok, for starters let’s try adding this to the CSS optimization exclusion field; * `mrtailor/css/app.css, mrtailor/css/default.css, mrtailor/css/styles.css, font- awesome.min.css` * frank * Thread Starter [lwkooy](https://wordpress.org/support/users/lwkooy/) * (@lwkooy) * [9 years, 6 months ago](https://wordpress.org/support/topic/optimizing-css-breaks-site-another-one/#post-8381500) * All right, that made some improvements.

But I tried excluding those quite sometimes already. No luck. * I’m in chrome, incognito to make sure I don’t hit the cache. The cions need to be in the header as well (now they are a bit half in the slider, half in the header). * No clue why he loads them twice as well. i think one set is in the theme and another one gets called from the visual composer plugin. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 6 months ago](https://wordpress.org/support/topic/optimizing-css-breaks-site-another-one/#post-8381730) * ah, had a look in chrome and see this one (and more like it) on the console; * > Access to Font at ‘[https://wordpress-ohiobear.netdna-ssl.com/wp-content/plugins/js_composer/assets/lib/bower/font-awesome/fonts/fontawesome-webfont.woff2?v=4.6.3’](https://wordpress-ohiobear.netdna-ssl.com/wp-content/plugins/js_composer/assets/lib/bower/font-awesome/fonts/fontawesome-webfont.woff2?v=4.6.3’); > from origin ‘[https://wordpress-ohiobear.netdna-ssl.com’](https://wordpress-ohiobear.netdna-ssl.com’); > has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is > present on the requested resource.
