Hello guys, recently i've update my website to php7.0, I'm runing some low minify CSS and JS. I encounter some css problems in Firefox & Internet Explorer with the all UI.
Any idea what causes this problem and how can be solve it please? With Chrome broswer works perfectly. Cheers, really appreciate ur help.

Found this isssue, was from my litespeed cache plugin/wordpress: "Load CSS Asynchronously" (Optimize CSS delivery. This can improve your speed score in services like Pingdom, GTmetrix and PageSpeed.) API: Elements with attribute data-no-async="1" in html code will be excluded.
