Won't load website properly

Hi,

Something just happened, I am not sure what is causing it…

My website (http://wildlifevagabond.com/) works for me, but I have done a few website speed tests using Google PageSpeed and GTmeterix and neither can get the page to load properly. Google even tells me that it could not show the visible content. I have just downloaded a couple of plugins to helpt me increase my speed and score, such as Async Javascripts (set to defer JS) and Remove query strings from static content. I did try other plugins as well, but when a few of them broke parts of my site I deactivated and removed them. These ones seemed to work perfectly, but all of a sudden the content began disappearing for others, but not for me… After deactivitng the plugins, I still got the same results… What is wrong, and how do I fix it?

Thanks,
Havard
