We are trying to share the results of the quiz on Facebook. The results should automatically populate the "share" box on Facebook and post. The preview is showing correctly, however when it is actually shared, the post reverts to just showing the website link and default website image (no text or designated image). This issue is occurring on each of the 4 quizzes and for each result. This was working correctly a few weeks ago, and suddenly stopped working.
Here's the link to the website: http://testyourchristmasspirit.com/ (sorry, can't link directly to the results page)
Thanks for any help!
