I will have to check this out but I think I might have missed part of the tutorial about the footer area when using this plugin widget….anyway, this is the Widget Output Template (in the widget) that I used:
{THUMBNAIL}{DATE}{EXCERPT}
The only thing is, that there is styling for this in the style.css file which has thumbnail colours, line 855:
#footer-group .widget_recent_entries li.posts-plus .wp-post-image {
padding: 0.250em;
background-color: #202327;
border:1px solid #4c4e52;
}
