Posts Links are Dead

i am running a site on

http://www.destinywebs.com/wordpress

i have added several posts which fall into various categories, and are accordingly displayed where required. however, when i click on these posts, i am taken to a 404 page. i have not set up any blog page, so i am sure there is something there, which i need to do.

an example of this can be found on my homepage:

http://www.destinywebs.com/wordpress – news slider: title links to nowhere. i do not know how to customize the links. the slider app is Theme Blvd News Scroller Widget.
the image slider on homepage – each of these images are fed through posts, however, when i click on the image, i get a 404.

PLEASE HELP!!!
