Hi,  
  
  
  
I installed version 2.2.1 and during the installation process, in the step after “Database Setup”, I get the following message:  
  
  
  
Fatal error: Interface ‘SymfonyComponentFormChoiceListFactoryChoiceListFactoryInterface’ not found in /home/…/…/vendor/symfony/form/ChoiceList/Factory/PropertyAccessDecorator.php on line 42  
  
  
  
Any idea how to fix this?  
  
  
  
Thank you!
