It great that it is fixed.

I disabled and re-enabled Cargo, and then, all the same. Maybe the database still need to be updated, because the error is still actually internal api error about database query error:

According to Yaron Koren, the database cargo_tables and cargo_pages are never created. To create them, stewards please help call update.php.

I asked the author Yaron Koren.

How to modify a namespace's standard name and display name (sometimes differs from aliases or stand name)?

The issue still exists.

Cargo is reopened on rs.miraheze.org, and still, it doesn't behaves well.

Sorry to be too late to respond. Actually, I have to prepare for the college entrance exam and have no time to maintain, so I disabled Cargo temporarily. I'll re-enable Cargo on the week several weeks later. Thanks.

@Hispano76 It also occurs. Sandbox of Template:沙盒.

OK. I use Cargo.

For example, group-confirmed/zh-hans and that in translatewiki; group-oversight/zh-hans and that in translatewiki.

1.29 updated already. But some of the translations are not updated. See here and here.

Thanks.
