@Ora: Can you please give an exception id (the hash)?

I can reproduce the delete issue.

I can't edit that page either, there's an alleged edit conflict.

I deleted the page server side

The page somehow managed to exist with no revisions. I've dropped it from the backend tables.

Please get an exception id for the import issue.

I found it.

@Ora: Please send the XML to sre@miraheze.org so I can run it in a debug mode

Done.

@Ora: Can you tell me where the dump is from so we can add a prefix

Same wiki, it's a backup.

It looks like the backup is corrupted.

Problem #2 is back.

I'll cleanup in a second. Have you tried the import again? It's the import leaving it broken causing it.

I did and then I deleted that file.

Please do not keep sending invalid imports. The file you've given will not work.

Removed again

I just created that page, exported it, deleted it and then tried to import it just to check.
"No revisions imported (all were either already present, or skipped due to errors)."
I assume you can reproduce this issue too.

...Same error with other pages. Brand new untouched XML files from this very wiki.

Please list the pages.

Please also give us the exact options you're using to export.

(And preferably don't try any more until we can fix this)

Okay.

All the mainspace pages:

Export:
*Include only the current revision, not the full history
*Save as file

Import:
*Prefix: superwiki
*Assign edits to local users where the named user exists locally
*No comment
*Import to default locations

Can I try again now?

I'll comment here when

I moved all of the mainspace pages with all of their history to a draft, and then successfully imported the last versions (there's no copyright problem). Everything seems fine. Thank you for your help.

This issue reminded me this old file. I don't even remember what it was and I don't need it anymore. Can you remove it?

Is there any reason you can't?

The page was deleted, but the file itself remained:
An unknown error occurred in storage backend "local-backend".
It still appears under "Unused files".

I've checked every place I can think MediaWiki would hold data but so far it still persists.

Whatever you did worked. You somehow deleted the older version so I was able to delete the newer version... and then there were none. Thanks!

Glad to hear it!
