When I try to access shortstories.miraheze.org, I get the following error message:

MediaWiki internal error.

Original exception: [5cb49419567b9ec0de07b6b9] 2021-10-14 21:43:01: Fatal exception of type "MediaWiki\Storage\NameTableAccessException"

Exception caught inside exception handler.

Set $wgShowExceptionDetails = true; at the bottom of LocalSettings.php to show detailed debugging information.

I imported pages from a backup (this is a re-creation of a wiki that was deleted some time after I exported its content to XML and closed it) about a few weeks ago (I think). I decided to come back to the site, and all of a sudden it shows this!

Please help me! The wiki has a lot of short stories on it (from various different people) that are unavailable anywhere else!
