Error: Anki does not show cards

Anki Help
1

Help! My anki will not allow me to access my cards and is displaying the error message below. I have tried going into my library and renaming collection.media.db2 in hopes that it would remake the file and solve the issue to no avail. I also tried deleting anki and redownloading it and that did not work either. I am not very anki savvy and would appreciate any help, especially if it was dumbed down and walked me through step by step.

It seems your collection is corrupted.
Do you use some sync/backup software? If so, you should not run it while Anki is open as that can corrupt your collection.

3

I’m not entirely sure. My anki usually syncs on it’s own when I exit out but I have not explicitly set up a backup software. I’m not sure how to tell for sure though. I’m sorry I don’t know how to tell you, but if that doesn’t answer your question can you try to help me understand how to?

4

I mean some external application used for backing up your collection/media to a service other than AnkiWeb.
If you’re not sure, maybe check other apps on your computer?

5

I checked my apps and I don’t think it’s backing up to anything else besides AnkiWeb

6

It’s good to do a secondary backup of the contents from time to time, just in case. I do that every two week’s or so, see Deck’s option menu.

Putting aside the question of how it happened (which could be hardware/OS issues), you should be able to restore either from an automatic backup, or your online collection if you were syncing with AnkiWeb.

Anki on my laptop has no cards and is displaying the below error. Anki on my iPad is working fine. I am not what sure what to do.

DBError { info: “SqliteFailure(Error { code: DatabaseCorrupt, extended_code: 11 }, Some(“database disk image is malformed”))”, kind: Other }

9

Some kind of file corruption, are you backed up to ankiweb? Local backups?

I’m backed up to AnkiWeb I think. Do you know how I can download it back or how to get my cards?
