Please don't scroll past this. This Wednesday, for the 1st time recently, we humbly ask you to defend Wikipedia's train.[0]

The new version is rolled back to group0 until we resolve:

• Error: Call to a member function getId() on null
• tl;dr: users can't login
• Already being worked on
• PHP Notice: Array to string conversion
• Impact unclear, maybe not a blocker

Once these issues are resolved train can resume. If these issues are
resolved on a Friday the train will resume Monday.

Thank you for your help resolving these issues!
