This plugin hasn’t been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WordPress Logger


Display log messages from PHP in the browser console in Safari, Firefox (with firebug), and Opera (with the new Dragonfly debugging environment). Essential debugging tool for
plugin and theme developers. You no longer have to use ‘print_r’ statements from PHP to figure out what is going
on in the code, which more often than not, messes up the DOM and HTML layout. Displays complex PHP structures like arrays and objects
in pretty print.


  • Log debug messages directly from themes and plugins.
  • Display log messages in the browser console, without muddying up the browser display.
  • Displays complex structures such as arrays and objects in pretty print.
  • Shows the line number and file from where the message was logged ( you won’t lose track of log statements ).

Code that forces the wplogger plugin to load first was adapted from the WordPress
FirePHP plugin
developed by Ivan Weiller.

This plugin is based on PEAR Log, the logging framework that is part of the
PHP PEAR library. Current maintainers Jon Parise, Jan Schneider, and Chuck Hagenbuch. PEAR Log is based on code first
developed for the Horde 1.3 framework – original authors Chuck Hagenbuch, and Jon Parise.
