Error 404 with Silex

Question

Talk guys, I’m developing a system for Web, I don’t really know how to handle web programming, but come on:

So all my controllers, index, htaccess, td right, so much so that the project is working normally if I run it localhost through phpStorm (that little code "php -S localhost:8080 -t www")...

But when I send this same project to FTP, the site opens normally, quiet, but only opens the first page, if I click on any link it gives the Error 404... This does not happen on the localhost, only when sending to the web. The strange thing is to work normally the first page, is a web system for very amateur box control, only for my use, but I wish I could use it when I was not at home too...

Access the site here (has even a vardump la kkk)

The folders are all in the right places, the paths are all right, I’m 2 weeks with the problem and I found nothing on the internet, really do not know what else to do... All right, so much so that it works local, I’m going crazy already...

I’ve even changed my hosting, before I was at a free Hostinger la... Now ta at Agilityhoster, also free. As it is a system only for me I want to leave it free for now...

What do you think it could be? Thanks

PS: The project was done with Silex, in that friendly URL scheme, where through the url falls into a "get" or "post" method within the classes...
