Temporary fix :
Use this code, add it in Child theme functions.php file or WPLMS Customizer/wplms_customizer.php file
add_action('bp_core_activated_user','myvibe_redirect_after_registration',99,3);
function myvibe_redirect_after_registration($user_id, $key, $user){
$bp = buddypress();
if ( is_multisite() )
$hashed_key = wp_hash( $key );
else
$hashed_key = wp_hash( $user_id );
if ( file_exists( BP_AVATAR_UPLOAD_PATH . '/avatars/signups/' . $hashed_key ) )
@rename( BP_AVATAR_UPLOAD_PATH . '/avatars/signups/' . $hashed_key, BP_AVATAR_UPLOAD_PATH . '/avatars/' . $user_id );
$bp->activation_complete = true;
wp_set_auth_cookie( $user_id, true, false );
$pageid=vibe_get_option('activation_redirect');
if(empty($pageid)){
bp_core_add_message( __( 'Your account is now active!', 'vibe' ) );
bp_core_redirect( apply_filters ( 'wplms_registeration_redirect_url', bp_core_get_user_domain( $user_id ), $user_id ) );
}else{
$link = get_permalink($pageid);
bp_core_redirect( apply_filters ( 'wplms_registeration_redirect_url',$link, $user_id ) );
}
}
