Deployement CakePHP3 shared server

Hello all,
I developped an application Cakephp3 in local with wamp server.
Now, I have to deploy into my sharing server but with my hoster (hosteur.com), I can’t use Composer or others kind of tools.
I transfered by ftp my project to my website but It doesn’t work.
How I can setup the project (path, htaccess…) to have a working project ?
Thank you

Please search, a while back a shared host question was answered. Also did you make sure host has minimum php requirements. On godaddy I just uploaded all, changed the database credentials and all worked right away. Double check the settings, etc.
