Install Issues

I installed via composer to a GoDaddy server on a subdomain.

When I go to subdomain.myurl.com the base site loads.

When I go to subdomain.myurl.com/requirements.php I get a path error.

When I make changes to .htaccess nothing works and I have tried over 35 different changes. All I can do it get a 500 error if I change rewritebase from /

when I try say subdomain.myurl.com/about it just reloads the index page.

I am lost of what to do or what I did wrong. Is there a better host where composer is already installed and I can just load Yii2 and go?
