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

Will add a little “x” next to any files/folders set to 777, since this is inherently insecure. Checks all recursive folders that come with a default WordPress install.
This plugin can be CPU intensive as it iterates over your whole folder/file structure to gather statistics.
Notes :
<ul>
<li>Checks root, wp-admin, wp-content, wp-includes and all sub folders</li>
<li>Includes your plugin and theme folders</li>
<li>Ignores images, text, CSS , and translation files</li>
<li>Will exclude the cache folders since they contain to many files to scan.</li>
<li>Requires PHP 5.1.2 or greater</li>
<li>Please run this during low traffic.</li>
</ul>
This plugin will not return accurate results under IIS or WAMP stack due to how windows handles file permissions.

File Permissions & Size Check

Simple plugin that checks your WordPress install and shows your file permissions, size, and last modified date.
