Black Bar

Black Bar is an unobtrusive Debug Bar for WordPress developers. It collects and displays errors, executed SQL queries, slow actions and hooks, theme templates, global variables, and provides a profiler.

How it helps you with development:

• Debug your code with the Console
• Inspect global variables (COOKIE, GET, POST, SERVER, SESSION, WP_Screen)
• Measure performance of your code with the Profiler
• View any PHP errors that occur when loading a page in the Console
• View executed MySQL queries along with execution time and backtrace
• View template files of the active theme in loaded order
• View the 50 slowest action and filter hooks along with callbacks ordered by priority
