Need help identifying a "related post" plugin causing problems.

Hi everyone,

It’s my first post here. I read through the rules beforehand and I’m pretty sure I’m in the right place.

I’m having some troubles with a plugin on my site that I need help with.

A couple of weeks ago I installed a “related post” plugin that I found from searching within my WP dashboard. Unfortunately, I don’t remember the name of the plugin, or this would be significantly easier right now.

At the time of installing, I realized I didn’t have enough posts to my site to make it effective. So I deactivated and then uninstalled it the same night.

Ever since then, I’ve had “related posts” showing up on any post I make. There’s no options to control this within the edit page, and there are no widgets or plugins I’m seeing that could be causing it.

I need help identifying which plugin it looks like, and what to do to remove these “related posts” from showing up.

An example can be viewed at the bottom of this post. Note it’s the one right above the “about the authors” box:

Thanks for all your help!
