Force [wordpress_social_login] shortcode to display where it is embedded [closed]

If you have a function that you cannot change to prevent the premature output, you can still override the shortcode handler:

add_shortcode( 'wordpress_social_login', 'wordpress_social_login_fix' );

function wordpress_social_login_fix( $attributes, $content ) {
    ob_start();
    wsl_render_login_form();
    return ob_get_clean();
}
