Major posting issue on my WordPress Site. Need help bad!

Background:
I’ve had my wordpress site up and running for a year (https://www.bonesnap.com)

Everything worked find until about 3-4 days ago. Now sure exactly when it started.

However, my issue is I can write a post and view it as a draft. However, once I publish the post this happens:

1. Can no longer preview it from the admin page, yet I can still edit it.
2. The post does not sort by date in the admin page.
3. The post does not float to the top of wordpress site
4. If you search for the post you will see it in the search results but if you click on the link you will get a error message.
5. All existing posts I can still edit and preview with out issue this is only for new posts.

I did now change my peralink structure. I verifed my .htaccess file also.

I am at a total loss on how to proceed or what I need to do next.

Any help is welcomed.

Thanks,
Ironspike
