Posts are Failing to Post

We’ve had a stable blog for several years-since 2006. Now we’ve notice that any posts made in June do not show up anywhere on our blog; not even in the askimet spam section. Any ideas?

We are able to create the posts and press the publish button with no error statements or other indicators of a problem. However when we view the site, or manage the site, there are no posts anywhere to be found.

I look forward to hearing back from the advanced intelligence existing on this planet. ??

Please know that I’m not a technical person, so please structure any advice/suggestions with that in mind.
