Blog out of order

Hi, I love this template and I used it for the blog of a non-profit organization. It was working perfect until some days ago that it all went out of order and now I cannot make it work again. I have no idea what can it be. I did not install new plug ins nor widgets, I had install some plugins for social media an other things before and it was working fine. I tried to install the google analytics code and install the title and header plug in for that, but it did not destroy the template.

Trying to fix the problem I had deactivated all plug ins and widgets, I had erase and install again the theme and still it looks all funky as if it was not loading or something.

Please any help will be appreciated.
