Buddypress not supported

Hi there,

I have buddypress enabled on my network, as you might know buddypress has its own registration form. I added class=”bpmvp-mail” to the email input field in my child theme in /buddypress/members/register.php
and also I added this function in my function.php file:

if ( function_exists( 'bpmvp_activate_third_party' ) ) {
	bpmvp_activate_third_party();
}

By testing the registration form, if I enter an invalid email, the form returns me the invalid email error. But If i enter a valid email address, the whole page reloads and nothing happens. Normally it should go one step forward to complete the registration. But it only reloads itself.

If I enable hook into is_email, Registration would continue (without any other changes). But each time a user logs in, it validates the email, and this behaviour eats lots of email checks in byteplant dashboard.

Please help me fixing this issue.
Thank you in advance
