I am not a programmer and normally has someone who does all of this for me. However, after a blogging conference, I took it upon myself to download Jetpack but since then, I cannot access my site from the admin side. I see the URL at the top of the page but the screen is white. When I go to my site it still exists, but I cannot get past the white page. I tried opening my site in chrome to change things up and it said it is either down for maintenance or not configured correctly.
What did I do and what do I do?
