How to Access the Back End of a Joomla Site
 

The back end is the interface where you will perform administrative functions for your site such as creating categories and articles, uploading images, installing extensions, etc.

1. To login to the back end of your site append /administrator to the end of your URL. For example, http://yoursite.com/administrator.
2. Login using your administrator username and password that were configured when Joomla was installed.
