Description

Error

MediaWiki version: 1.36.0-wmf.14

message
Class 'TranslatablePage' not found

Impact

Over 60 of this just now in a spike, in group0. This seems like a clear programming error, and as such I'm going to make it a train blocker, as it looks like it'd cause manylots errors in group1 and group2. If my analysis and guess is wrong, please tell me.
