 * Hi [@bling007](https://wordpress.org/support/users/bling007/),
 * It seems the customer set a phone number as the billing email. Maybe that is 
   how the OTP plugin works, removing the email validation for the email field.
 * 1. Does this happen with the OTP plugin disabled?
 * 2. If so, what OTP plugin are you using?
 * Best,
    Diego

 * There is no OTP plugin in use anymore. OTP plugin is disabled.
 * Which OTP plugin I was using?
    Digits.

 * Hi [@bling007](https://wordpress.org/support/users/bling007/),
 * The line below from your error log shows that the system tried to set what looks
   like a phone number to the billing email field:
 * `#1 /var/www/html/wp-content/plugins/fluid-checkout/inc/checkout-steps.php(2884):
   WC_Customer->set_billing_email(‘9920685007’)`
 * Maybe this entry was added to the log while the Digits plugin was activated.
 * 1. Could you confirm that these errors are added to the log file even when the
   Digits or any other OTP plugin is deactivated?
 * 2. Could you send a step-by-step on how we could reproduce this problem on our
   end?
 * Best,
    Diego
