I’m not sure what means ‘mobile wheel’, i checked your site but i see you have been deactivated it.

Can you tell me or give me the plugin?

add this to the additional css section

.site {
	max-width: 100% !important;
}
.site-header {
	max-width: 100% !important;

}
#site-header img {
    width: 100% !important;

}
