Error installing laravel 5.6 app on remote hosting

Try /var/log/apache/access.log or /var/log/apache2/access.log or /var/log/httpd/access.log. This are apache logs, see what's there!

I was having similiar issues, beside storage there is bootstrap folder to set chmods

your Log folder is owned by root and is not writable by anyone else

in your /var/www/html folder, run

sudo chown -R www-data:www-data box-booking

Thank you for your hints! I opened /var/log/apache2/error.log file and found error that vendor directory was absent I pulled vendor directory and I got on screen error that some fields in tables were absent.

I created new database with fresh db dump and set name to this db in .env file.

But the browse opened only error:

This page isn’t working
139.59.34.234 is currently unable to handle this request.
HTTP ERROR 500

I opened /var/log/apache2/error.log and see errors like

Why errors and how to fix it ?

Also a question : have I to add /vendor/ dir into git or is it autogenerated?

No you don't add vendor to your git version control.

You add composer.lock and composer.json

When you install, you must run composer install --no-dev. It will look at composer.lock and pull in all the vendor packages that you used in development (except for those you marked as development only in composer.json)
