A must plugin for admins, developers, and support staff that use <a href="https://wordpress.org/plugins/elementor/" rel="ugc">Elementor Page Builder</a>. Debug Elementor helps you save time and effort when trying to figure out what’s wrong with Elementor.
Instead of hardcoding debug snippets, writing complex code to return post meta data from the database, or trying to remember the credentials to you sites phpMyAdmin, you can simply use this plugin to display all the relevant post data stored by Elementor.
Debug Elementor provides information visible from the sites front-end. This way external experts can help you troubleshooting issues with Elementor. The plugin displays basic post data and other related information when you are debugging your page. You get basic post data and additional data saved by Elementor.
See whether the post is using Elementor or not, see the CSS generated by Elementor for each post, and the entire elements structure – including all the sections, the columns, the widgets and all the saved data!!
To display the post data just add <code>/feed/elementor/</code> to the post/page URL:
<pre><code>https://your-link.com/post-slug/feed/elementor/
</code></pre>
Note that if you are trying to view the data on your browser, it’s strongly recommended to use JSON decoder like <a href="https://chrome.google.com/webstore/detail/json-formatter/bcjindcccaagfpapjjmafapmmgkkhgoa" rel="nofollow ugc">JSON Formatter</a> for Chrome.

For admins, developers, and support staff, Debug This provides a ton of information about your WordPress installation, all from the front-end admin bar.
<ul>
<li>The current WP_Query object</li>
<li>Blog info and options</li>
<li>Embed providers</li>
<li>Files in rendered HTML (CSS, images, JavaScript)</li>
<li>Filters and actions</li>
<li>Images sizes</li>
<li>Globals and constants</li>
<li>Menus</li>
<li>Object cache stats</li>
<li>Plugins, must-use plugins, and dropins</li>
<li>Rewrite rules</li>
<li>Queries</li>
<li>PHP and server information</li>
<li>Post attachments</li>
<li>Post types</li>
<li>Scripts and styles enqueued</li>
<li>Shortcodes</li>
<li>Sidebars and widgets</li>
<li>Taxonomies and terms</li>
<li>Themes</li>
<li>Users</li>
<li>WP cron schedules and jobs</li>
<li>WP debug log</li>
</ul>
Debug This helps you save time and effort when trying to figure out what’s going on. Instead of hardcoding debug snippets or writing complex unit 
tests for small functionality, you can simply bring to the surface what you need right from the admin bar.
For example, when viewing a single post, you can see:
<ul>
<li>a list of post attachments,</li>
<li>which menus and sidebars are being displayed,</li>
<li>the post type, post fields, and meta data,</li>
<li>the current query variables and query string,</li>
<li>the rewrite rules applied,</li>
<li>the author,</li>
<li>the terms,</li>
<li>and much more.</li>
</ul>
<h3>Extend</h3>
<h4>Debug This Functions</h4>
New debug modes can be created easily:
<pre><code>add_debug_extension(
 $mode,
 $menu_label,
 $description,
 $callback,
 $group = 'General'
);
</code></pre>
Example
<pre><code>add_debug_extension(
 'actions',
 __('Actions', 'debug-this'),
 __('$wp_actions contains all active registered actions', 'debug-this'),
 'foo_callback',
 'Filters And Actions'
);
function foo_callback($buffer, $template){
 global $wp_actions;
 $debug = print_r($wp_actions, true);
 return $debug;
}
</code></pre>
You can add links to the header of a debug mode page. Place this code within your debug callback function.
<pre><code>add_debug_header_link('http://urltolink', 'Link Label');
</code></pre>
Extensions can be removed as well using <code>remove_debug_extension($mode);</code>
No PRE Tags
If you don’t want your debug output to be enclosed in PRE tags, simply set the following in your extension:
<pre><code>Debug_This::$no_pre = true;
</code></pre>
Saved Queries and Execution Time
Retrieve saved queries and execution time by using the following static properties:
<ul>
<li><code>Debug_This::$execution_time</code></li>
<li><code>Debug_This::$queries</code> – SAVEQUERIES must defined as true</li>
</ul>
URL Helpers
<ul>
<li><code>Debug_This::get_current_debug_url()</code> – current URL with the debug query</li>
<li><code>Debug_This::get_escape_url()</code> – used for the debug escape link that links to original page URL</li>
</ul>
<h4>WP Actions</h4>
<ul>
<li><code>debug_this</code> – receives the $mode arg – outputs the debug code sent from the extension modes. The default action is set to priority 5. This allows you to prepend or append any output without conflict using less or greater priorities.</li>
</ul>
<h4>WP Filters</h4>
There are a few filters you can use to customize Debug This to your needs:
<ul>
<li><code>debug_this_template</code> – receives $template arg – Use your own template</li>
<li><code>debug_this_default_mode</code> – receives $mode arg – Alters the mode for the parent DT admin bar button link.</li>
<li><code>debug_this_output</code> – receives $output, $mode args – Filter debug content before it’s rendered</li>
</ul>
<h4>JavaScript</h4>
To access the built-in Debug This JS functionality, enqueue your custom script with the dependency set to <code>debug-this</code>. Your script will inherit a jQuery dependency.
Object: debugThis
<ul>
<li><code>debugThis.mode</code> – current mode</li>
<li><code>debugThis.defaultMode</code></li>
<li><code>debugThis.template</code> – current included template</li>
<li><code>debugThis.queryVar</code> – the defined query string variable</li>
</ul>
Functions:
<ul>
<li><code>isDebug()</code></li>
<li><code>getDebugMode()</code> – uses <code>isDebug()</code></li>
</ul>
Events:
A jQuery <code>debug-this</code> event is fired from the footer. You can hook into this event with the following;
<pre><code>jQuery(document).bind('debug-this', function(event, debugThis){
 console.log(debugThis);
});
</code></pre>
<h4>Helper Functions</h4>
There are three included functions to help you work with files.
<ul>
<li><code>debug_this_get_file_ownership($file)</code> – returns <code>array('name' => $name, 'group' => $group)</code></li>
<li><code>debug_this_get_file_perms($file)</code> – returns string – Example: 0775</li>
<li><code>debug_this_convert_perms_to_rwx($perms)</code> – returns string – converts permission number to RWX format – Example: 0755 folder becomes drwxr-xr-x</li>
</ul>
