303: Allowing e-mail re-use in phpBB
The entered email address is already in use.
This error occurs when you try to enter the same email address multiple times when registering user accounts. When you are running tests on your user registrations and you need to allow multiple email addresses, you can change a setting in phpBB to allow it. This article will explain how to prevent this by setting the "Allow e-mail address re-use" option to Yes in phpBB.
Allowing Multiple Identical Email Addresses
- Log into your phpBB Admin Control Panel (ACP).
- On the general tab, Click the User registration settings in the Board Configuration.
- Click the Yes radio button next to the "Allow e-mail address re-use" option.
Save the changes.
