For what it’s worth, I had problems also when installing to asmallorange hosting.
I was cloning from github.
The issue was that I needed to change the files to chmod 644 and folders to 755, essentially. Specifically, I changed .htaccess to 644, index.php to 644, panel/index.php to 644, and panel/ to 755.
If someone could explain why this was the case, I’d be interested to hear
