All,

I'm hoping the gurus on the Mailing List here can help. I'm a big user of Duplicator on the wiki I help take care of, but it looks list some recent upgrade in MediaWiki is causing an issue. I've upgraded to the latest Duplicator I can find (Duplicator-REL1_32-5158b26.tar.gz) and I still get the error.

When I try to Duplicate a page I get an "Internal Error" and:

[XIKDya3smIUAAHYHRiAAAAAV] /wiki/index.php?title=Special:Duplicator MediaWiki\Revision\RevisionAccessException from line 1635 of /home/geos/geos5.org/wiki/includes/Revision/RevisionStore.php: Main slot of revision 4281 not found in database!

I will note that Wikiapiary says I might be the first 1.32 install to try it (https://wikiapiary.com/wiki/Extension:Duplicator).

Any ideas on what might be going on?

Thanks, Matt
