It was a performance boosting plugin that destroyed your CSS and JS through minifying it, but that happens when minifying stuff. 😉 I can’t remember the name, it was just marked as performance in the Sidebar.
Hey, thanks so much for the quick answer, I think Ive found the conflict, but sadly the other plugin is required by the theme, so I cant remove it, thats why I had to disable the plugin 🙁
Thanks so much anyway!
