WordPress Debug Bar

With version 3.1 of WordPress comes the Admin Bar, which we introduced in a previous article, and this also allows to add your own entries. And so there is, created by the development team of WordPress, a Plugin for additional information available. The Plugin Debug Bar docks on the Admin Bar and gives, with one click on the new menu link, additional details of the installation.
These include the query, cache, PHP messages and hints and tips for obsolete functions.

None of the data is contextual new; they were already available for developers, but displayed in a more readable way. Until now you have to use one of the free Plugins, which did the job for you and output all necessary information.

The Admin Bar is in backend and frontend available and makes a fast access to backend areas possible. This advantage applies also to the Debug Bar.
