Conversion Failed

Delete your downloaded manga and clear cache then backup again, after that backup should be within 300MB

[waicool20]

Seems like a bad backup, how big is your backup?

[Skelletonike]

I get a a similar error.
A dozen or so mangas show up as processed before the error occurs.
The backup file is roughly 1.27GB, even though I've already cleared all data and downloads.

[Skelletonike]

I had tried clearing cache several times but it never worked somehow.
In the end I decided to try delete the app and do clean install with an online backup.
This time around the ad file was only 34mb and it managed to pick up convert properly (1200ish manga).

Guess the size really was the problem. Thanks for the tip.

[Wizard1134]

Deleting my downloaded manga reduced my file side from 2.1gb to 1.8gb; after that everything worked as intended.

Maybe just having downloaded stuff is the issue.

[DoPlusSee]

Hey I've had the same problem, i'm not sure if my file is still too large, I have already cleared my cache and deleted the downloaded manga and still failed to convert. Mangarock DB file size is 33,920 KB
