Hello,
You need to move the block. On public side click on an arrow
Find my widget. Drag and drop on sidebar area.
That's for old version.
For new
Latest. When I release a new version you will install it using this button
I can tell you the trick to show widget in certain forum. PM me if you need it.
If you mean "One problem Ive found is that it can't display images from a subforum?" I fixed it already. Version 1.0.6.
When you enabled 1 post per topic
Open /plugins/nb40recenttopicsposts/widgets/nbRecentTopicsPosts.php
Find
$wherePosts[] = array('forums_topics.last_post=forums_posts.post_date');
Change to
$wherePosts[] = array('forums_topics.last_real_post=forums_posts.post_date');
