WP posts only loads header and no content or sidebar? (host monster issue?)

I was just trying to publish a post on my blog and I started noticing some problems.

At first, when I would hit the publish or preview button, the page would just show an empty white page. I would hit publish and it would redirect me to a white page with nothing, so I had to hit the back button to go back to my dashboard.

Then, all of a sudden the publish tab worked and post was published.

Then I went to check the site live, and all of my pages and posts were giving me 404 error. A few minutes later, pages are showing ok, but posts don't show up. The page for posts loads only the header section and no content or sidebar.

Does anyone know whats going on? Is it host problem? Or is it something on my end?....

I did deactivate all plugins, but had nothing to do with it. plus, last night everything was working fine and I didn't change anything (files, etc) since last night.

I am thinking its a database issue or something like that, but I am not techy.

By the way, I am with HostMonster and a few days ago hostmonster was down for 7-8 hours. So that makes me think there may be something wrong on their end.

But I just wanted to see if anyone else having such problem, or if anyone could tell me if there is something wrong on my end (in files, database or something like that).

Thank you in advance.
