BuddyPress.org

Just solved using WP registration because no way to use register page

I added bp-custom.php in /wp-content/plugins

this is code:

/**
* Disables BuddyPress’ registration process and fallsback to WordPress’ one.
*/
function my_disable_bp_registration() {
remove_action( 'bp_init', 'bp_core_wpsignup_redirect' );
remove_action( 'bp_screens', 'bp_core_screen_signup' );
}
add_action( 'bp_loaded', 'my_disable_bp_registration' );

add_filter( 'bp_get_signup_page', 'firmasite_redirect_bp_signup_page');
function firmasite_redirect_bp_signup_page($page ){
return bp_get_root_domain() . '/wp-login.php?action=register';
}
