Problem when using facebook comment.
Web language: Vn
<div class="fb-comments" data-href="https://###.com/vn/sony/ong-kinh-sony-fe-70200gm.html" data-numposts="5"> </div>
Web language: En
<div class="fb-comments" data-href="https://###.com/en/sony/sony-fe-70-200mm-f28-gm-oss-lens.html" data-numposts="5"> </div>
There are 2 different comments on 1 product due to different urls.
I use
<div class="fb-comments" data-href="{$urls.current_url}" data-numposts="5"> </div>
