FAQ

I’ve installed the plug-in, but can’t figure out how to make a particular post “sticky” for a selected category.

First, see this article from WP Beginner for making sticky posts

Any sticky post should now show up on top of the category page that the post is categorized in.

I’ve installed the plugin and made a post sticky. Sticky posts are still not showing up in the category page.

That probably indicates that the category page is displaying posts using a custom loop. The plugin is designed not to kick off on custom loops.
