I forgot a minor detail where the code will allow duplicate email address thus cause an duplicate entry error in mysql since the email tests do not check for case sensitivity. The problem can be easily fixed by forcing all email address entries either at initial registration or profile updates to lowercase. Here is what you need to change.

file: include/register.php v1

find this section of code

# mod.use.email.rather.username
# check if email already exist in customers table      
        if( $email == func_query_first_cell("select email from $sql_tbl[customers] where email='$email'")) {
                # duplicate email not allowed
                $eerror = true;
        }

and replace with

# mod.use.email.rather.username
# check if email already exist in customers table
        $email = strtolower($email);
        if( $email == func_query_first_cell("select email from $sql_tbl[customers] where email='$email'")) {
                # duplicate email not allowed
                $eerror = true;
        }
