"Site is Offline" Facebook sharing error Featured Image wrong

Hi all, and happy new year.

Please check this out. My blog is new (8sentences.com) and I’ve been building. Only yesterday did I ever really try to share to Facebook.

Here are the 2 problems in one, that I experience trying to share to Facebook…When I try to share whether using sharing buttons or pasting the link…

1 – FEATURED IMAGE shown but “SITE IS OFFLINE” – It shows SITE IS OFFLINE instead of the snippet and READ ON tag.

2 – FEATURED IMAGE WRONG – Post title and snippet are shown, but instead of the featured image my site icon picture ‘8’ is shown.

3 – NO FEATURED IMAGE AT ALL, JUST SITE IS OFFLINE – Some don’t show any featured image or title or snippet at all, just “site is offline”.

Here is a post I created to show you images of the 3 possibilities I get when trying to post, all erroneous.

NOTE: I’m using the BBird Under theme and I used the Site Offline Or Coming Soon plugin but now even upon deactivating it I still have this Facebook display problem.

Any assistance will help. Thanks.
