Hi,
I don't know if other Ikea websites suffer from the same problem, but here's an example of incorrectly blocked content: http://www.ikea.com/be/nl/catalog/categ ... Mattresses
Note the URL used for the pictures:
http://www.ikea.com/ms/nl_BE/img/ads/vitality/national_promotion_area/binnenveringsmatrassen.jpg
Would the word "ads" be the culprit?
