Whenever I share a page on my website (every page has different content/info) Facebook does not detect/present the photos (thumbnails), only a one sentence description. How can I get these page thumbnails detected? I have found loads of threads about this issue in the Yola help forum but they are all, like, several years ago... actually, it worked for a few weeks and then nothing! Please help as I often share events and news pages on social media sites. I did the FB debugger btw, plus tried to change the 'header' (in Tracking) but this took my whole website offline!!!
