I can't post links to my wordpressWordPress site on my facebookFacebook business page. The urlURL does not contain any unusual or sensitive worlds (www.genesiskravmaga.com). When I try to post the link, there is no option for adding a thumbnail image and when submitted I get the "oops, something went wrong" message. I've seen this error reported elsewhere but have never seen a solution. Is it a facebookFacebook problem or do I need to add some code to my site to allow facebookFacebook to post the link?
