There is no need for my email address to create a user.
You can just type an non-existing email address.
Click on Show password and copy the password for me
Uncheck the send user email setting.
By the way, are you using latest reduxframework plugin?
And did you set the header and footer pattern via Appearance -> Theme Options -> Styling -> Header and Footer
and Not via Appearance -> Customize ?
Because, sometimes Appearance -> Customize does not work properly in this theme.
