I just published a post as per usual and noticed some things about it which are probably related to the ongoing missing post issue.
I always use the New Post link from the drop-down list of my blogs on the Admin bar. I used it to create a new post called Ruralopolis Here I Come, and hit Publish as per usual. I noticed when I went to the published page via View Post that the URL had a numerical suffix, ie raincoaster.com/=20389303 or such. The Share buttons did not show on the post, which I, being a famewhore, noticed immediately. On a hunch, I went to raincoaster.com and yep, the post was not visible. I went back to the Edit page and hit Publish and then it showed up at raincoaster.com just fine.
The blog I need help with is raincoaster.com.
