Erreur nouveau type de contenu

Bonjour,

J'ai un gros problème, j'ai installé drupal commerce kikstar, et quand j'essaye de créer un nouveau type de contenu il m'écrit ce message d'erreur :

"Additional uncaught exception thrown while handling exception.

Original

PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: SELECT s.lid, t.translation, s.version FROM {locales_source} s LEFT JOIN {locales_target} t ON s.lid = t.lid AND t.language = :language WHERE s.source = :source AND s.context = :context AND s.textgroup = 'default'; Array ( [:language] => fr [:source] => Add a customer profile [:context] => ) in locale() (line 684 of /Users/axoune/projet_site/sites/drupal_v3/modules/locale/locale.module).

Additional

J'ai la dernière version de MAMP (je suis sur un serveur local)

Merci d'avance
