Website Not Showing Up

I went to download phpbb 3 from Softaculous and I didn’t direct it to https://www.example.com/forums and it prompted me to overwrite these 2 files that I cant remember. Now https://www.example.com has nothing on it except a thing from my web host. Please tell me I can recover my site and put it back to where it was. Thank You

– Is the name of my website.
