This question already has an answer here:
I have a working symfony project on my linux computer.
I'm trying to set it up with hosting www.one.com
I wrote a .htaccess file but I'm getting the following error:
Fatal error: Cannot declare interface Symfony\Component\DependencyInjection\ContainerAwareInterface, because the name is already in use in /customers/x/x/x/xxxxxxxxxx.be/httpd.www/var/cache/dev/classes.php on line 6397
Can anyone help me in the write direction?
ps:
I followed the guide http://trac.symfony-project.org/wiki/InstallingSymfonyOnOne but it does not seems to be working.

A guide which you are following is about Symfony 1.x, interface you mention is from Symfony 2 so you have a mismatch here. Try to follow this guide (and remember that Symfony 1.x and 2.x/3.x has nothing in common).
And just a guess: try to clear the cache on your new machine:
app/console cache:clear --env=prod
