Product Reviews of different languages grouped together in the same page

How can I group the reviews even if they are from different languages?
I have 4 reviews in Portugal Portuguese and 1 in Brasil Portuguese and I would like to show the 5 reviews together!
I edited both header_php.php from includes/modules/reviews/pages/product_reviews and product_reviews_info

and removed the lines:

AND pd.language_id = :languagesID

and

  $review_query_raw = $db->bindVars($review_query_raw, ':languagesID', $_SESSION['languages_id'], 'integer');

but it still doesn't group together.

Any idea?
Thanks!

I think you are changing the SQL query associated with the product information, not the reviews' information. You probably want the product description and name to appear in the language that the current customer has chosen. To display the multiple language reviews, try changing this section (/includes/modules/pages/product_reviews/header_php.php):

  $review_status = " and r.status = 1";

  $reviews_query_raw = "SELECT r.reviews_id, left(rd.reviews_text, 100) as reviews_text, r.reviews_rating, r.date_added, r.customers_name
                        FROM " . TABLE_REVIEWS . " r, " . TABLE_REVIEWS_DESCRIPTION . " rd
                        WHERE r.products_id = :productsID
                        AND r.reviews_id = rd.reviews_id
                        AND rd.languages_id = :languagesID " . $review_status . "
                        ORDER BY r.reviews_id desc";

  $reviews_query_raw = $db->bindVars($reviews_query_raw, ':productsID', $_GET['products_id'], 'integer');
  $reviews_query_raw = $db->bindVars($reviews_query_raw, ':languagesID', $_SESSION['languages_id'], 'integer');
  $reviews_split = new splitPageResults($reviews_query_raw, MAX_DISPLAY_NEW_REVIEWS);
  $reviews = $db->Execute($reviews_split->sql_query);

to this:

  $review_status = " and r.status = 1";

  $reviews_query_raw = "SELECT r.reviews_id, left(rd.reviews_text, 100) as reviews_text, r.reviews_rating, r.date_added, r.customers_name
                        FROM " . TABLE_REVIEWS . " r, " . TABLE_REVIEWS_DESCRIPTION . " rd
                        WHERE r.products_id = :productsID
                        AND r.reviews_id = rd.reviews_id " . $review_status . "
                        ORDER BY rd.languages_id, r.reviews_id desc";

  $reviews_query_raw = $db->bindVars($reviews_query_raw, ':productsID', $_GET['products_id'], 'integer');
/*  $reviews_query_raw = $db->bindVars($reviews_query_raw, ':languagesID', $_SESSION['languages_id'], 'integer'); */
  $reviews_split = new splitPageResults($reviews_query_raw, MAX_DISPLAY_NEW_REVIEWS);
  $reviews = $db->Execute($reviews_split->sql_query);
