@gmail.com' domain is disallowed. Please choose a different email.
Hi Kris,
"JomSocial Denied domains is empty. it wont allow any registrations, its very weird."
It is caused for the backend admin panel > jomsocial > configuration > site > Registration > Allowed Domains
You have allowed there only "fanspam.com".
See the screenshot.
You may have allowed more domain with comma separated or empty for all domain.
Thanks
