Post Disappeared

I created a post a while back and it disappeared publicly. All that showed was a image with the same title of the post. Since the post was still in my Dashboard I simply copied the information and made a new post with a similar name but with adding a number and deleted the non-showing post.

My old post was:
http://www.onesteptoweightloss.com/shakeology-reviews

and then I created:
http://www.onesteptoweightloss.com/shakeology-reviews-2

It worked fine and I could see the post publicly… Then I check today and now http://www.onesteptoweightloss.com/shakeology-reviews-2 is having the same issue as before.

What can be causing this issue? There haven’t been any new plugins since then.

Thanks.
