Follow these steps and you'll never fail at anything 

• Install JUGA using our installation instructions
• In JUGA>>Groups, create an "Administrator" and a "Super Administrator" group
• In JUGA>>Configuration, set:
  • default_juga: "Public Access"
  • public_juga: "Public Access"
  • default_juga_admin: "Administrator"
  • juga_superusergroup: "Super Administrator"
  • flex_juga: "Public Access"
  • flex_ce: www.yourdomain.com
  • default_ce: [leave blank]
• In JUGA>>Site Items, click the "Synchronize" button.
  • Set display = '100' in the page navigation area at the bottom of JUGA>>Site Items
  • Click the checkbox in the titlebar to select all the checkboxes on the page
  • While all the checkboxes are checked, click "Flex +" to assign the Site Items to "Public Access"
  • Browse to the next page in the page navigation
  • Repeat this process until all your Site Items are assigned to "Public Access"
• In JUGA>>Variables, set Auto-Add=YES for the 'id' variable for com_content, Front-End
• Enable the JUGA System Plugin in the Plugin Manager

At this point, you've configured JUGA so that your site operates as if it weren't even installed!

To restrict access to your articles and components, remove "Public Access" from the corresponding Site Item and assign another group to it!
