Hey, so I recently saw that luckperms v5 was released and decided to update.

Upon updating, I was greeted by the following error: https://ghostbin.co/paste/yoje8

Our luckperms db is about 750mb (yes I made a backup).

Thanks.

Can you try running it by generating a new folder? Just rename your current LP folder to something else then restart the server.

It generates fine.

I'm going to assume your storage is corrupt.

You say you have a backup, did you run the /lp export <file> command? If so, you can just run /lp import <file> after putting the exported file into the new LP folder.

Oh, I assumed when updating it would be fine, weird, maybe add a spot for that somewhere in the upgrading to v5, you only guys only mention making a backup. It also runs fine on v4.2.58 :P so I don't think it's corrupt.

Also, after exporting the data from our v4 version I get a file with no extension.
When I try to import this into v5 I get the following error: http://i.iconictech.net/18.51.40-28.11.19.png

It does update just fine. You just happened to be unlucky and it corrupted at the same time you updated.

Regarding the error:
The export format did change.
So downgrade to v4, import the data and the upgrade again. Then everything should work.

I'm sorry I'm a little confused, you said downgrade to v4 then export, but I did export that on v4. v5 doesn't allow me to import whatever I exported from v4

No I did not. 😜
I said downgrade, import, upgrade. Also wipe the storage before importing.
