This plugin is great for someone needing to debug their own or another person’s WordPress site. It will collect and display and/or send debug information to an email address provided by the user. 
This is helpful for plugin or theme authors wanting to debug user’s sites.
Some features:
<ul>
<li>Displays system information</li>
<li>Emails system information</li>
</ul>
<h3>Arbitrary section</h3>
You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated 
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or 
“installation.” Arbitrary sections will be shown below the built-in sections outlined above.
<h3>A brief Markdown Example</h3>
Ordered list:
<ol>
<li>Some feature</li>
<li>Another feature</li>
<li>Something else about the plugin</li>
</ol>
Unordered list:
<ul>
<li>something</li>
<li>something else</li>
<li>third thing</li>
</ul>
Here’s a link to <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> and one to <a href="http://daringfireball.net/projects/markdown/syntax" title="Markdown is what the parser uses to process much of the readme file" rel="nofollow ugc">Markdown’s Syntax Documentation</a>. 
Titles are optional, naturally.
Markdown uses email style notation for blockquotes and I’ve been told:
<blockquote>
Asterisks for emphasis. Double it up for strong.
</blockquote>
<pre><code><?php code(); // goes in backticks ?>
</code></pre>

WordPress Debug

Displays and emails system information for debugging purposes for easy debugging of your own or a client/user site.

Saves you from asking “have you emptied your cache?”.
Forked and updated for todays WordPress and PHP from the original plugin by Paul Clark.
Features
<ul>
<li>Safe to leave running on live sites.</li>
<li>Only refreshes browser cache for a file if it has been modified.</li>
<li>Resolves Content Delivery Network (CDN) issues. No need to purge CDN cache.</li>
<li>Multisite compatible.</li>
<li>“Just works” – no configuration necessary.</li>
</ul>
Requirements
Requires scripts use any of the below functions to load. Almost all files meet these requirements. The only case it doesn’t account for is when URLs are hard-coded. This shouldn’t ever be done, since it can break sites for other reasons.
<ul>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_style" rel="nofollow ugc">wp_enqueue_style</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/wp_enqueue_script" rel="nofollow ugc">wp_enqueue_script</a></li>
<li><a href="https://codex.wordpress.org/Function_Reference/get_stylesheet_uri" rel="nofollow ugc">get_stylesheet_uri</a></li>
</ul>

reBusted!

I always have one or two clients where "its still not working for us"

This is the plugin that solves that. 

Recommend developers/agencies everywhere install this and save them and their clients a bundle of time. 

Thanks for keeping this alive after the last Busted version went AWOL. 

Thanks for keeping this alive


This is a great tool for advanced developer. It saves you from manually versioning your css/scripts or devising your own versioning solutions based on system time which would reload css/js every time, slowing a page load. This ensures only changed styles/scripts are reloaded. Five stars!


A must

Force browsers to load the most recent file if modified.
