[Plugin: Seo by Yoast qTranslate] Doesn't works

Hi there,

I’m trying to use qTranslate with Seo by Yoast, because I need to have 2 languages in my site.

I did the official solution: https://yoast.com/wordpress/plugins/seo/faq/#why-doesnt-the-wordpress-seo-plugin-with-qtranslate

function qtranslate_filter( $text ) {
  return __( $text );
}

add_filter( 'wpseo_title', 'qtranslate_filter', 10, 1 );
add_filter( 'wpseo_metadesc', 'qtranslate_filter', 10, 1 );
add_filter( 'wpseo_metakey', 'qtranslate_filter', 10, 1 );
add_filter( 'wpseo_opengraph_title', 'qtranslate_filter', 10, 1 );

But it doesn’t works to me, I can’t see something diferent.

Next I tried is to modify the class-frontend.php:

else if ( $this->is_home_posts_page() ) {
			$title = $this->get_title_from_options( 'title-home' );
// Changes start here
// Changed to tackle multilingual issue on posts page
		} else if ( $this->is_posts_page() ) {
			global $q_config;
			$title = qtrans_use($q_config['language'], $this->get_content_title( get_post( get_option( 'page_for_posts' ) ) ), true);

// Added to tackle multilingual issue on pages
		} else if ( is_page() ) {
			global $q_config;
			$title = qtrans_use($q_config['language'], $this->get_content_title(), true);
// end changes
		} else if ( is_singular() ) {
			$title = $this->get_content_title();

It works, but not completely, because I can change the SEO Title (with [:en]) but no the meta description.

I tried to put <!–:en–>Meta description<!–:–> and it doesn’t works, when I update the page, the code disappears and I see, for example:

What I’m doing bad? I followed this thread: http://wordpress.org/support/topic/plugin-wordpress-seo-by-yoast-compatibility-with-qtranslate?replies=39

Thank you!
