Magento 2 Message d'erreur lors du vidage du cache

Question

Je cours Magento 2.0.7. Quand je suis dans le back-end et je tente de vider le cache à l'aide « Flush Megento Cache » ou sélectionner tous les dossiers de cache et cliquez sur Actualiser je reçois un paquet blanc avec l'erreur ci-dessous:

There has been an error processing your request 
Exception printing is disabled by default for security reasons. 

Error log record number: 707031421789 

Le site continue de fonctionner , et magento reconnaît que le cache est effacé lorsque la notification disparaît. Mais son ennuyeux et je ne sais pas si sa compensation en fait tout cache ou non

le rapport d'erreur montre le détail ci-dessous:

cela fait référence à la ligne 508 de file.php qui a le dessous

Answer 1

Je suis sûr que vous avez depuis longtemps résolu cela, mais pour la postérité je viens fixe un problème très similaire à 2.1.5 en supprimant le contenu de var/cache. Puisque vous essayez d'effacer les caches, cela ne devrait avoir aucun effet secondaire.
