All works well, until I uploaded the code and cam

Answer 1

For me worked installing symfony/intl

"symfony/intl": "2.5.5",

php composer.phar update symfony/intl

Answer 2

Symfony 2.3 requires the intl extension to be version >= 4.0 ( a version greater than 4.4 at best ) because of it's dependency to the symfony/intl component.

Composer will download different versions of symfony/intl and lock these in your composer.lock depending on your development ICU version.

This means if you develop on a system with ICU greater than 4.4 you won't be able to install on a server with ICU < 4.4.

Please read the documentation chapter ICU and Deployment Problems.

Update your intl extension as suggested in my answer here:

sudo aptitude install php5-intl 

... or add

"require: {
    "symfony/icu": "1.0.*"
}

to your composer.json.
