CMS After upgrade to 4.0.2. articles are missing from the front page
 

We post to our blog/cms daily. We posted 6 new articles on the 26th, all were showing fine on the front page (CMS). After we upgraded, we only have 3 articles showing dated 2/25, 2/22 and 2/21. Why did it remove articles with the upgrade from the front page?

I just tested it and I can't get any of the articles to post on the HOME page. What needs to be done to fix this?
