Broke my website after changing http:// to https:// on settings

This is regarding the website filmsfortheforest.org wordpress. I changed the URL in the wordpress settings to say “https://” instead of “http://” and I seem to have broken the site. Is there a way someone at wordpress can restore a previous backup of the site to before I made this change?

Even when I try to login at filmsfortheforest.org/wp-admin, it redirects me to another website’s wordpress instead of the wordpress for filmsfortheforest.

Please help me fix my site, thank you!
