How to Restrict unregistered users from accessing any of the Joomla website?
As far as question goes:
- There is option to disable the website in global configuration
- Go to permissions page of the global configuration
- Allow "registered" user group to "access site" when it's offline (allowed to admins only by default)
Good grief, so much offered when so little is asked.
No, taking the site offline restricts access to all but Super Users.
Who cares why he wants to do it. He asked if it can be done.
Here's a simple way to restrict access. It is written for J2.5 but the idea remains the same. Set permissions to be restrictive.
