@krinkle @juergen_hubert It does seem like version 12.0.0 lists "partial" 1.44 compatibility in its readme, whatever that means.

@krinkle @juergen_hubert I do not see any commit that looks like it might have fixed it in the git history, and the ticket you shared was closed by the reporter after they were told the issue would not be fixed and they should stick to the LTS version. So no, I don't think it is fixed on the git main branch and I don't think running some random wip commit from Github in production is a good idea anyway.

@krinkle @juergen_hubert Their policy seems to be to only support LTS releases of MediaWiki, so official support for 1.44 is unlikely.

@juergen_hubert this is a complete shot in the dark but errors like that often result from version incompatibilities, or missing plugins - are you sure all plugins you are using are compatible with your current MediaWiki version?

@juergen_hubert check your logs for the actual error message, to begin with
