Suddenly only 1 post appears on main blog and it is not the most recent post

Hello,

So, with no other changes having been made to this otherwise very stable blog last weeks post

http://www.fetchlocalcustomers.com/b...mmerce-charge/

has taken over the main blog posting page. Normally this page:
http://www.fetchlocalcustomers.com/blog

would display the 10 most recent posts but it automatically displays the aforementioned post only.

If I "trash" this post the main blog page gives me "page missing" error.


My most recent post:

http://www.fetchlocalcustomers.com/b...the-superbowl/

Displays just fine if you go to its category.

Please help!

I have tried everything I can think of and I am stumped!
