Indeed i don't think it's really broken, but haven't found a better way to call this.
This happens in all blogs except one --where they show properly if js minification enabled.
I'm using platform theme.
Logo is a png image uploaded through template setup inside the Site Branding module. Slides are shown with Promotion slider plugin, which shortcode is included in platform's module Universal Sidebar.
I guess i've tried so far to exclude all js files (both platform and promotion slider's) one by one but this hasn't work.
So maybe the solution is somewhere else?
