It is hard for novice WordPress users to find out what the backbone of their hosting is made up of. Some plugins may require a specific version of the PHP scripting language or a certain version of the MySQL database management software.

Diagnosis adds pages to the Dashboard menu where the main administrator of the WordPress installation can view technical data about the server in an easy manner along with a suitable explanation. Most fields also have a link to an appropriate Wikipedia article.

This plugin is predominantly based on the original Diagnosis plugin: http://nlindblad.org/wordpress/diagnosis/



  • Part of the Diagnosis screen.


  1. Upload the diagnosis folder to the /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Visit Dashboard -> Diagnosis to see the information.
