I found reason why section is invisible. This section tag ends with: style=”display: none;”
<li id=”accordion-section-sidebar-widgets-sidebar-big-title” class=”accordion-section control-section control-section-sidebar control-subsection” aria-owns=”sub-accordion-section-sidebar-widgets-sidebar-big-title” style=”display: none;”>
Removing this fragment from code shows the menu element but doesn’t make it work.
There are more mistakes in code.
So, in my opinion, this is a problem with the theme code.
Fix it, please.
