Creating users in version 10.0.10.4

HI, when I try to create a user in version 10.0.10.4 it keeps saying “Error creating user, invalid email address”. I also by chance installed yesterday the previous version where we used username and password and it worked fine. I have changed php to 7.1 from 5.6 and it makes no difference. Any help gratefully received. Thanks.
