ok, you need to get this code into your site.

@media screen and (max-width: 400px) {
.list-view .site-content .cat-links, .list-view .site-content .entry-content, .list-view .site-content .entry-summary, .list-view .site-content footer.entry-meta {
    display: initial !important;
}

}

There are many ways to do this.

If you theme has a custom css area, you can put it in there

Otherwise you can look for a css plugin and add that

or you could install and activate my style pack plugin

bbp style pack

and go to

dashboard>settings>bbp style pack>custom css and put the code in there
