Admin Can Always Comment

I use this on CSS-Tricks for the obvious reasons. I close comments after a certain amount of time, but as an admin, I want to be able to leave comments whenever I want to. 

Works Great with 4.9.6

This plugin allows an admin user to add comments even if the comment thread is closed.

Permissions & Security Audit is a plugin that runs a series of tests to check common security issues with the following areas:
<ul>
<li>File and folder permissions</li>
<li>File and folder ownership</li>
<li>WordPress configuration settings</li>
<li>Apache/PHP and hosting settings</li>
</ul>
Although this plugin will flag potential issues; it will not resolve these items. You will need to manually resolve them, use the help of a plugin or contact an individual who has the experience to help.
Ce plugin est disponible en français aussi.
