By default your devZing Bugzilla is configured to be private. That is a user must log in before they can see a defect.

If your project is open to a wide audience you may want to let anyone view bugs. This can be accomplished by changing the requirelogin parameter.

From the Bugzilla Main Page, navigate to:

Administration / Parameters / User Authentication

Scroll down the page to this field:

Change as appropriate and click Save Changes at the bottom of the page.

You will want to also review the self registration settings. See
