Plug-in Not Working

I’ve spent several hours trying to activate a few different plug-ins for my blog. None of the plug-ins work even after activating and updating the setting for each one (i.e. social buttons, contact page, etc). The theme I’m using is by Arcsin and blog is at http://www.savvyandbroke.com.

I’m not a developer, therefore I have limited knowledge on how to setup webpages using codes. Hopefully I will not have to create and embed too many codes in order customize my blog in the way I would like.
