Website not displaying

I am new to this. I had a wordpress.com blog (it is still up) https://www.thisgreenlife.wordpress.com. I signed up for midphse they are hosting my wordpress powered blog, https://www.this-greenlife.com. I did the automatic transfer on their site. I went to try and get all the pages to post (becuase they were not working). Now my site will not come up at all. It is just a blank page.

Does anyone know how to help me? I think once I get it up and running I will be fine, but right now I’m completely lost and about to give up.

Thanks.
