Multilanguage Post Titles not Translating with List Category Posts Plugin [closed]

I found a hint towards the solution exactly where you advised me. I think the solution was a bit outdated, but with a bit of digging, I made the following change:
in file include/CartListDisplayer.php, in function get_post_title() I added the following code in first line before anything else:

if ( function_exists( 'qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage' ) ) 
{ 
    $single->post_title = esc_html(
        qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage( $single->post_tit‌​le )
    ); 
}
