About the login redirect. It is also possible using custom code. Set the login page URL in Downloads > Settings > Frontend and add the following code to your theme’s functions.php file. Replace the place_your_url_here with the actual redirect destination URL. Now users will be redirected to this URL after login.
add_action( 'template_redirect', 'wpdm_login_redirect' );
function wpdm_login_redirect(){
if( is_user_logged_in() && get_the_ID() == get_option('__wpdm_login_url') ):
wp_redirect( "place_your_url_here" );
exit();
endif;
}
