Check Apache error log. You'll find a fatal error.

Check that Apache user has write permission on that folder

What user Apache used?

permission already 755, but for root:root
I don't know which user that apache used.

You'd better study how Apache works before publishing sites, otherwise you'll encounter errors or (even worst) security problems. Never make root own published folder, privilege escalation attack would be easy
apachectl -S, which will show something Apache user and group
