Ok I will check this. Here are the list of activated plugin I have :
-All in One SEO Pack & qTranslate-X
-Better WordPress Minify
-Coming Soon Page & Maintenance Mode par SeedProd
-Contact Form 7
-Cookie Notice
-Fusion Builder
-Fusion Core

-HTTP Headers
-qTranslate-X
-Simple Custom CSS and JS
-Slider Revolution
-Watcheezy WordPress Plugin

I didn’t install these, like I said the website was already created. I’m here to make it responsive and add extra pages/articles.
