Drupal 8.x

Hello,
I'm writing to you because I have a very annoying problem.
This morning I made a few changes to my site, and then cleared the cache. To make sure everything was working, I went to my site's home page but got the following error message: “The website encountered an unexpected error. Please try again later.”
I went back into the settings and changed the site redirection from “mysite.com/node” to “mysite.com”.
I logged out...
Now I can't log in at all. I can no longer access the mysite.com/admin/login page.
Can you please help me?
