Web is gone after I tried to install Wordpress?

Hi! I created https://lopezbaeztrad.000webhostapp.com/ on Jan 20th for a Uni project and today I thought I should install Wordpress onto my computer to translate something that I didn’t manage to do so with plugins. So I logged into 000webhost>Manage Site>Install Wordpress and I was asked for a new admin name/password and after that my site was just gone. Missing, ciao, adios. When I tried to log into Wordpress again an error message saying I had no permission to access that site showed up. I don’t know what to do or how to get it back but I believe that password thing had to do because I didn’t do anything else apart from that. Now when I go to Wordpress everything is brand new and my pages and plugins are not there. Any help please? Thank you so much.

You installed WordPress 2020-01-20
You then again freshly installed it 2020-01-26 17:29:41

Thankfully it didn’t overwrite and created a new database.

I have restored the previous configuration.
