Permission problems

[caffeine]

I'm really going crazy about the permissions.

I tested all possible combinations, but I'm getting this error:

Espo.ERROR: Uncaught exception {"exception":"[object] (Espo\\Core\\Exceptions\\Error: Permission denied in data/cache/application/ormMetadata.php at /application/Espo/Core/Utils/File/Manager.php:190)"} []

or sometimes I get:

Espo.ERROR: Uncaught exception {"exception":"[object] (Espo\\Core\\Exceptions\\Error: Metadata::setOrmMetadata() - Cannot save ormMetadata to a file at /application/Espo/Core/Utils/Metadata.php:300)"} []

Any ideas? This start after the 2.8.0 update.

Is not permissions, it was because I had an empty array in the config.php: 'quickCreateList'.
