Project hosted

@emilio,

Is your system on Hostgator configured that same as your system on your computer?  Are both systems using Apache web server? Are your permissions correctly set on the hosting server?

Yes, both are using Apache web server and both are using the same version og CodeIgniter 3.1.9.
Both are configured with the same configuration. 
Don't know why on Hostgator url helper doesn't work and I miss pages.
Mine is a simple project with some Controllers and some Views (None Models and no use of Database), 
and autoload of 'email' and 'url'.
I don't know if probles is about version of PHP (I use 7.1 version) or becouse on Hostgator I am using HTTPS.

Thank You php_rocs
