This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Debug Objects


The Plugin Debug Objects provides the user, which has the appropriate rights, normally the administrator, a large number of information: query, cache, cron, constants, hooks, functions and many many more. Values and content get displayed at the frontend and backend of the blog, to analyze errors but also to better understand and develop with/for WordPress.

The Plugin provides in various tabs information to:

  • PHP
  • Memory usage
  • Load Time
  • Included Files
  • Operating System
  • Server
  • WordPress Version
  • Language
  • Very extensive definitions of various constants
  • Cookie definitions
  • Separate user and usermeta tables
  • FTP and SSH definitions
  • WP Requies, only data with values, for the current request
  • Detailed Query information
  • Query information about the active plugins, nice to identifier the longrunners on the plugins
  • Query information about all queries from wp-content-directory
  • Conditional tags; value of the tag
  • Roles and his capabilities
  • Theme information
  • HTML Inspector is a code quality tool to check markup. Any errors will be reported to the console of the browser. This works only on front end. use HTML Inspector
  • Translation debugging helper
  • Template Information
  • Cron content and his functions to an cron
  • Cache content
  • Hooks and filters
  • All options from table, for single and multisite installation
  • Time values for inspect Permalink Rules
  • Rewrites, a list of cached rewrites and the rule
  • Current screen information to find the right backend page and hook
  • List Custom Post Type Arguments
  • Functions, which respond on hooks and filters
  • Contents of arrays to hooks and filters
  • All defined constants
  • All classes
  • All shortcodes
  • List transients
  • Post Meta data
  • See data from $_POST; $_GET and debug backtrace before rewrite; usefull for forms in backend
  • Run WordPress in default mode via url-param
  • Support (WP Fields API)[]
  • WooCommerce, list current hooks and template arguments.
  • and many more …

The plugin does not filter values and should only be used for information and optimization, I don’t recommended to use it on a live blog. For developers it can rapidly deliver data, which is useful in a development environment.
There are no data in the database and there are no settings. Therefore, the installation is pretty simple: Just upload the Plugin in the Plugin directory or use the automatic installation of the backend to install and activate the Plugin. In the footer of the frontend of the blog, you can see the information.

If you want to know what goes on in your website's background then this is the plugin you need. It does exactly what it says it will do. There was an issue but the developer was quick at fixing the issue. Well done, keep up the great work. Kind regards

Debug Objects provides a great abundance of debug info. It’s my standard debug tool I rely on for every customer site or product install that I have to debug in customer support. Thanks! 💐✨🍫
