Here’s a new plugin to add to your WordPress developer toolbox. Debug This gives WordPress super admins the ability to access debugging information through the admin bar on any page. Not only does it display errors, it also gives you a succinct summary of what scripts, styles, actions, filters, queries, etc. are active on the selected page.
Debug This displays valuable debugging information in a tidy, readable screen that’s easy to close out.
These are just a few of the debug modes included in the plugin:
Variety of WP_Query modes
Variety of PHP modes (defined functions, constants, classes, phpinfo, etc…)
