About page where you published search_edocman module, indeed there seems to be JS conflict between it and our [=] menu. Please ask Edocman developer for details OR consider if you really need to use edocman search module. Maybe there is a different way to show all indexed content.
Problem can be also caused by JS compression that you used. Can you exlude main.js file from it?
BTW
Use also that Custom CSS
@media screen and (max-width: 580px) {
#sp-header.menu-fixed #offcanvas-toggler,
#sp-header.menu-fixed .icon-top-wrapper {margin-top: 20px;}
}
It will fix location of [=] icon on mobile view.
