AllPages View as Home Page Now

I am not sure what is going on, but when I click through to the various pages on my website, they all show as the Home page(Welcome, on my site).

Today I created a new post to my News section. It showed fine in the Preview stage, but when I went to look at it as a reader on hte website, the page was blank, except it showed up with a header called “Products.”

Recently, I added the WP e-commerce plug in. I activated it, but do nothing further. I have now deactivated it, wondering if that might have been the conflict(since this was the last thing I did, and everything was fine before that).

After deactivating the plugin, the “News” page then changed to be as the Home page.

Thanks for any assistance.
