center 2nd top menu

Hey!

It’s because of this code you have in Quick CSS:

#header_meta .sub_menu {
    float: none !important;
    margin-left: auto !important;
    margin-right: auto !important;
    padding-left: 0 !important;
    width: 550px !important;
}

Wrap it with a media query so it only affects the desktop view:

@media only screen and (min-width: 767px) {
#header_meta .sub_menu {
    float: none !important;
    margin-left: auto !important;
    margin-right: auto !important;
    padding-left: 0 !important;
    width: 550px !important;
}
}
