nebojsab on "[Plugin: SideOffer] Hide Plugin on Mobile"

Have you tried with style i posted?

@media screen and (max-width: 480px) {
    #sideoffer {
        display: none !important;
    }
}

I'm looking at your site, and i can't see this setting anywhere? This peace of code placed in your theme style sheet will completely remove sideoffer from browser view.
