Hi, If, you did a backup while cells is running, you may get a corrupted boltdb file. In this case, boltdb of pydio.grpc.docstore service is corrupted. You must clean this db before starting cells. Once you get the login page, try to create new user using `./cells admin user create` > Don’t forget to `export CELLS_WORKING_DIR=/var/cells` > If you are running in Fedora, please try to disable SELinux > Don’t remove `.minio.sys` ---

Hello @c12simple, thanks again, > In this case, boltdb of pydio.grpc.docstore service is corrupted. You must clean this db before starting cells. Therefore, I deleted `/var/cells/services/pydio.grpc.docstore` as you suggested here [Restoring Cells from backup and getting an error on logs - #2 by c12simple](https://forum.pydio.com/t/restoring-cells-from-backup-and-getting-an-error-on-logs/7206/2) This time, I started cells with `--log=debug` as you suggested and get the following errors on the log. ```auto 2025-04-03T10:26:47.016+0300 ERROR pydio.server.manager ✗There was an error while starting:server.Start grpc: listen tcp 127.0.0.1:8031: bind: address already in use ``` ```auto 2025-04-03T10:26:37.696+0300 ERROR pydio.grpc.search Cannot start queue, using an in-memory instead {"error": "leveldb: manifest corrupted (field 'comparer'): missing [file=MANIFEST-000357]"} ``` After receiving **Unauthorised** error on web I got the following log ```auto 2025-04-03T10:31:19.105+0300 ERROR pydio.rest.frontend Policies blocked POST request at /a/frontend/session.

Hello @c12simple. I am sorry for taking your time. The whole time, the issue was with the SQL backup file. I don’t know how, but it was broken when I copied it to the new server, therefore, I just reuploaded the file and restored it. Now it is working. Thank you so much for your time. ---

Hello @c12simple Just out of curiosity, doesn’t the restore include the activity of files? Like the time it created and modification activities? After I restored it and I couldn’t see any activities on the right pane. Instead, new activities are only starting to register and be shown. ---
