It's bug somewhere in your theme CSS.
Best way to resolve that is to reinstall your theme or use another one.
what is your forum url, which version of MyBB you are using & which theme ?
forum url : cms.bgbox.eu
version 1.8.x
theme ; flow

I've used rocket loader without issue for MyBB. I don't think that's the biggest issue.
I thinks the problem is that the forum is a 1.6.x version of MyBB:
http://cms.bgbox.eu/jscripts/general.js?ver=1603
And the Flow theme it's for 1.8x series
fixed thanks guys
Reason : because the version of mybb is 1.8.x and the theme is for 1.6.x
