By default your devZing Bugzilla is configured to not allow users to self register for accounts. If you wish to enable this feature do the following:

From the Bugzilla Main Page, navigate to:

Administration / Parameters / User Authentication

Scroll down the page to this field:

To allow anyone to self register for an account enter “.*” (without the quotes).

To prevent self registration blank the field.

If you want to allow only people with email addresses at your organization to self register change it to: “^.*?$” without the quotes and substituting your own domain.

If you are disabling self registration you may also want to require that users log in before they can see anything. See
