Can't type post

I can get to the New Post screen, and I can type a title. But I can’t get my cursor to move into the area to type the actual post. I’ve tried both clicking in the New Post area and tabbing after the title, but neither will allow me to enter anything. It’s been working fine up until the last day or so. Also, the Dashboard loads very slowly. My site is https://www.stephaniemeddleman.com
