مدیریت پیکربندی کلی
From Joomla! Documentation
The Global Configuration area is part of the administrative interface, accessed via http://example.com/pathtojoomla/administrator (also referred to as the “backend”). This area is accessible only if you are logged-in as a member of a group having the attribute of being Super Administrators (by default the Super Users group only). Once logged in, to access the page go to System → Global Configuration or click the Global Configuration link from the main control panel.
