Hello again!
This is a one solution I found and it works.
Use the Simple Custom CSS plugin.
Then add under appearance > Custom Css the following code:
@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: inline;
}
}
This is me again:
Remove .list-view .site-content .cat-links if you dont want category link to show up
I found the solution on the thread two pages before this one on 2014 topics page.
