Exhibit page affecting whole website - can't delete

Hello,

jordanmouzouris.xyz

One of my exhibit pages is not working and I'm unable to delete it. It's affecting the whole website and none of my exhibit links are working as a result of this one page. I tried to insert some coding to experiment with the title and think that's affected the whole website. Can someone advise me on how to solve this?
