How to remove questions category

Hi mate, sorry for my late reply.

I have checked your site and see that this is breadcrumbs from your site. I this case, I think you can add the following code.

.singular-dwqa-question nav.breadcrumb-trail.breadcrumbs {
display: none;
}


Also, you can install the following plugin to add/edit css code: https://www.ads-software.com/plugins/simple-custom-css/
Hope this helps!
