Account creation error: The domain "domain.tld" already exists in the user data.

Symptoms

When attempting to create or restore an account, you encounter an error similar to the following:

CONFIG_TEXT: Failed to create the account: (XID 6shq2n) The domain “domain.tld” already exists in the userdata.

Cause

This error frequently occurs after a domain has been removed from the server, but an entry for it still exists in the /etc/userdatadomains file.

Resolution

1. Access the server's command line as the 'root' user via SSH or Terminal in WHM

2. Backup the /etc/userdatadomains file by running the following command:

   # cp -av /etc/userdatadomains{,.$(date +%s)}

3. Run the updateuserdatacache script:

   # /scripts/updateuserdatacache --force
