Plugins generally not working

I have just set up my blog, and am realizing that most often my plugins just plain do not work. I have tried out shadowbox, various “share” plugins and other things rated 5 stars and verified as working.

It seems like some of the share ones will work on “Pages”, but not on any of my posts in my custom template. Shadowbox wont work at all, as well as my page numbers plugin, and many others.

Can someone please take a look at my code and see if i did something wrong?

<?php
