Apologies for being so new to all this, but I have Yoast installed and running and I have added the options to use Open Graph and Facebook/Twitter card but it seems that Yoast has not modified the heard at all. Is should modify header.php in my theme to include the meta informaiton correct?
When I test the system, with facebook or twitter, it is clear that the tags are not working. Any help would be great and apologies for noob status again.
