Links are not correctly formed, for example, you have -

<a data="-"  toggle="collapse" parent="#vopros-otvet" href="#accordion-one-link-5"><h4 class="panel-title">

but you need:

<a data-toggle="collapse" parent="#vopros-otvet" href="#accordion-one-link-5" class="collapsed" aria-expanded="false">
