Map went white

My map has been working beautifully for well over a year. But I made a change yesterday and it just went white. I can’t click on any of the states in the back end, and nothing is clickable on the front end. I don’t know why it did this. All I did was update a link. How can I fix it? Please don’t tell me everything is just gone, I don’t have backups of the content.
