Posts in dashboard not appearing

Hey there all!

I’m enjoying some succes with my wordpress 3.5.1. site https://dutchreview.com

However, I’ve ran into some serious problem. I had blank pages before when I tried to login, always some updated plugin. But now I’ve encountered something else. I had a spelling error which I tried to edit in the most recent article, but after clicking ‘update’ the page went blank. And now as well, when going to the ‘all posts’ it doesn’t show anything.

Also, we finished switching hosting-companies yesterday. That could also be it.

Any suggestions? Thanks a lot!
