Changed domain in WordPress

Hey people,
I’ve recently changed the domain in the WordPress configuration that was hosted on 000webhost… but it seems that my page is now broken, and I can’t access either the new page or the old one.
Old one: https://maciejowos.000webhostapp.com/
New one: https://zenlooptest.000webhostapp.com/

I guess I made a mistake when changing the domain to the one that doesn’t exist…
And when I try to login to my admin via https://maciejowos.000webhostapp.com/wp-admin, it tries to redirect me to the new domain, but it doesn’t work - and I can’t log in…

Is there any way to somehow change the domain back to the old one, or do I have to remove it and install it again?
I had some nice content there and I don’t want to remove it :frowning:
Thanks a lot!

Change your URL to your actual URL in the database and your site will work as before.
