I'm using Last Viewed Posts (LVP) plugin on a qTranslate-enabled website. LVP shows post titles in both languages. I found this hint: titles in recent posts appear together in all languages with qtranslate

But not sure how to apply this filter. Relevant code in LVP:

        foreach ($zg_post_IDs as $value) { // Do output as long there are posts
        global $wpdb;
        $zg_get_title = $wpdb->get_results("SELECT post_title FROM $wpdb->posts WHERE ID = '$value+0' LIMIT 1");
        foreach($zg_get_title as $zg_title_out) {
            echo "<a href=\"". get_permalink($value+0) . "\" title=\"". $zg_title_out->post_title . "\">". $zg_title_out->post_title . "</a>, \n"; // Output link and title
        }

Instead of echo $post->post_title; it has $zg_title_out->post_title.

Replacing the whole zg string with apply_filters('the_title',$post->post_title) didn't work.
