Hellooo!
Probanly because in your theme: /minamaze/styles/style-responsive.css
The code on line 135 says:
#pre-header-links-inner, #breadcrumbs, #sidebar, #intro.option3 .page-teaser, #footer-menu, .meta-author {
display: none;
}
– If you change it to:
#pre-header-links-inner, #breadcrumbs, #sidebar, #intro.option3 .page-teaser, #footer-menu, .meta-author {
display: block;
}
It will most likely show your sidebar and widgets on the mobile device!
