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.

This is a tool to understand your rewrite rules (“Pretty Permalinks”). It is indispensable if you are adding or modifying rules and want to understand how they work (or why they don’t work).
It is only an analyzer, it does not change any rules for you. It parses the rules down to their components and shows the connection with the resulting query variables. It allows you to try out different URLs to see which rules will match and what the value of the different query variables will be (see screenshots).
This plugin was written as a tool to help answering questions about rewrite rules on <a href="http://wordpress.stackexchange.com/" rel="nofollow ugc">the WordPress Stack Exchange</a>.

Monkeyman Rewrite Analyzer

Throws a warning if WP_DEBUG is on, other than that still a very handy tool to check your rewrite rules.

Very useful

Helped me sort some issues with the rewrite rules when developing a plugin. Works fine with WordPress 5.2 and does what you need it too.
