Interestingly, if I go back to any prior posts, before those that went in the last 18 hours, I can manually share to Facebook, and the correct image shows. It is only posts from between 10pm last night and 6am today.
Looking at your most recent post, I don’t really understand what’s causing the issue:
- The post includes all the tags Facebook requires to build a post preview: http://i.wpne.ws/ZHr0
- When looking at that post in Facebook Debugger, I get an error telling me that there is no
og:url tag for that post, although we’ve seen above that the post does include the tag: http://i.wpne.ws/ZIAi
- On that same debugger page, Facebook shows us that Facebook previews include the Featured Image: http://i.wpne.ws/ZILE
- Yet when looking at the post on Facebook, it doesn’t include an image: http://i.wpne.ws/ZIHj
- When I try to share that post on my timeline, it doesn’t include anything: no image, no description.
- You mention that you don’t have that last issue on your end.
I know you don’t like to hear that from me every 2-3 months, but I’m afraid I can’t help you there. Facebook has all the information it needs according to its “Sharing Best Practices” page, and yet it provides 4 different results for that one page.
I don’t see any recent issues in Facebook’s platform status page, so at this point I’m afraid I can only direct you to Facebook’s bug report tool:
