You may need Google Translate:

Problème identique rencontré sur une 1.7.6.7

Solution :
- Se connecter en ftp
- Aller dans /src/PrestaShopBundle/Resources/config/services
- Renommer adapter par _adapter
- Récupérer le dossier adapter d'un ZIP PS 1.7.6.7 tout propre
- Mettre ce dossier adapter dans le dossier /src/PrestaShopBundle/Resources/config/services

Le back-office est de nouveau accessible.
