While operating "Special:Movepage" on my wiki, MediaWiki reports this error output.

System Versions:

MediaWiki	1.39.3
PHP	8.1.13 (fpm-fcgi)
MySQL	8.0.24
ICU	70.1
Lua	5.1.5
Pygments	2.11.2

I'm not sure how to resolve this problem, and I need help. Thanks a lot!

Sounds like a bug in extension:Lingo

I resolved it by removing the following line from LocalSettings.php

wfLoadExtension( 'Lingo' );

I'll report this error to Extension_talk:Lingo anyway

I feel like i've heard this error message before, but i could be mistaken. I would also suggest trying the latest version of lingo to see if it got fixed recently.
