After successful installation a white screen using URl mysite/grav/admin

I am new to Grav installation via Filezilla.

To upload I opened the grav-admin folder on the desktop and extremely carefully dragged all files into my grav folder I had made and located in /var/www/html, as prescribed by my hosting company. When I entered in Firefox, mysite.com/grav/admin, it came up with just a white screen but that is better than the, “site not found,” that I was getting in my other attempts. I couldn’t find a public_html folder on Ubuntu 24 Noble which is what my server runs in order to have a LAMP stack. I don’t know if an .htaccess got left behind or permissions were not correct. I had not uploaded since shared hosting eleven years ago and this is a VPS so it is new. I only need some guidance if possible. This places my grav folder at /var/www/html/grav. Did I get this right or do I try, try again? I just want a little success at something rather new to me. Thank you so much, ACrowe

Empty screen usually means there’s an error, but error output is disabled. Check logs or enable error output
