Hi,

seems you have some issues with your SQLite database. A sane thing what you should do is to convert your database to a real database like MySQL or PostgreSQL (especially when using encryption). The needed steps are documented here:

Before enabling encryption please also read and understand this:

Encryption keys are stored only on the ownCloud server, eliminating exposure of your data to third-party storage providers. The encryption app does not protect your data if your ownCloud server is compromised, and it does not prevent ownCloud administrators from reading user’s files. This would require client-side encryption, which this app does not provide. If your ownCloud server is not connected to any external storage services then it is better to use other encryption tools, such as file-level or whole-disk encryption.

mmm…I can do it but, is it going to fix the problem? I think that in this way I’m not going to recover my files

Revert to your backup before you have updated the keys, migrate to MySQL and optionally disable encryption afterwards if you don’t use external storages like Dropbox.
