Topic on Extension talk:Lingo

Issue could not be reproduced.

My previous thread on Support desk: Topic:Xhcx9i52jjtxukye

While operating "Special:Movepage" on my wiki, MediaWiki reports this error output. The version of Lingo is 3.2.0. After disabling Lingo from the LocalSettings.php, the error output disappeared. So I'm pretty sure it's Lingo's bug.

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 wonder if it's related to PHP 8. We'll see if we can reproduce this.

@WrOffi, I've not been able to reproduce this. Does the page you're moving have translations?

Can you share with me some steps on reproducing?

I've tried moving a regular page without translations and it works well. Looking at the backtrace, I see something related to the translate extension so I want to be sure because this could be affecting translation pages with Lingo.

Possibly related to Extension:SpamBlacklist (There was a somewhat similar issue with a different extension that only showed up when SpamBlacklist was installed).

I've tried to disable SpamBlacklist and reactivate Lingo, but it shows up the error again.

After disabling Lingo, everything works fine

@WrOffi, my suspicion is that this could be related to the Translate extension together with Lingo. When I have Lingo in isolation, it works fine but seems on translation pages, this causes the issue (have not yet reproduced it since I don't have the extension locally).

If you disable the Translate extension, does the "move" action work?

I think the best way to test this is to disable all other extensions and see if the issue still exists. If not, enable extensions one at a time until you find the culprit.
