Clear the Akeneo cache
After making changes to Akeneo, it is highly recommended to clear the cache to avoid problems. Run these commands:
$ cd apps/akeneo/htdocs $ php bin/console cache:clear --no-warmup --env=prod
It is very important to apply read, write and execute permissions (recursive) to the cache folder after clearing the cache if you are running it with root privileges.
$ sudo chmod -R 775 var/cache
