Installation

  1. Upload the plugin to the “/wp-content/plugins/” directory.
  2. Activate the plugin through the “Plugins” menu in WordPress.
  3. Activate the plugin itself in “Tools” -> “F12 Profiler”.

Important: The plugin will not track anything before activated by yourself (see the steps above). This will allow you
to disable the plugin within the options without uninstall and install it all the time if you require it.
Also, it will only be activated for logged in users that are able to manage options of plugins.

If you have any further questions do not hesitate to ask.
