I am having this link: http://www.myqourse.com/offer/557/en/Certificate+Business+Professional+-+CBP+Leading+through+change
when I post it on WhatsApp, the link renders perfectly. However, Facebook tries to fetch http://www.myqourse.com/www.myqourse.com/offer/557/en/Certificate+Business+Professional+-+CBP+Leading+through+change
Any thoughts why is this is happening?

Solved it! I had a pretender.io middleware, that, was not compatible to my new htaccess. I updated the htaccess and removed pretender.io and forgot to do that to my middleware!
