<ul>

<li>New thumbnail sizes are registered</li>

At <a href="https://wowpress.host/" rel="nofollow ugc">WowPress.host</a> company we regularly migrate very old databases and clean it up to make sure website using it is running smoothly. Those databases have all different kinds of inconsistencies collected during years or even decades of usage, and Media Library is the most common problematic piece of data here. 
That plugin helps to solve most common problems related to Media Library data.
We use a lot of open-source tools in our work, and therefore decided publish our own tools so that those can be used by the community too.

Fix Media Library

This plugin is legitimate.  Works perfectly.  Of course, with everything you do in WP related to the database and files; you should ALWAYS pull your own backups.  However, I had no need to use them.  It worked the first time and did a miracle for a client's site I was working on.

Amazing. Flawless.
