See this (one of many examples): https://en.wikipedia.org/w/index.php?title=User_talk%3AArsenalFan700&type=revision&diff=760410329&oldid=759997226

This looks like https://gerrit.wikimedia.org/r/#/c/311856/
"We'll have to coordinate the deployment of the code with the new template content." - oops?

Hm. Without a doubt, though, the issue has been troublesome to message
receivers and off-putting to curators recently. I appreciate your looking
into it.

The only production wiki where this is deployed is English Wikipedia hence I do not see any justified urgency here.

@JustBerry: As you raised the priority of this task, do you plan to write a patch?
Asking as resources of teams are limited when it comes to working on requests. We want to be realistic about communicating what is being worked on, to maximize the impact of changes. Practically, this often unfortunately means assigning a low priority to many tasks.
If the priority was increased because you plan to work on this task please claim the task by setting yourself as assignee. Thank you for your help!

@Aklapper The English Wikipedia has quite a lot of articles created (and hence pages being curated) relative to other wikis. However, I understand limitations in the team's resources. Thank you for claiming the task, @Mattflaschen-WMF.

FYI, another report just came in: https://en.wikipedia.org/w/index.php?title=User_talk%3AJustBerry&type=revision&diff=760948801&oldid=760618979

Just as an FYI, its getting more reports are coming in on the page curation talk page. I'm sure its the same bug, but just putting it here as an FYI: https://en.wikipedia.org/w/index.php?title=Wikipedia_talk%3APage_Curation&type=revision&diff=761417151&oldid=761182075

@Etonkovidova, reminder to check into this one (no hurry).

Thanks, @jmatazzoni.

I've imported NewPagesFeed_Templates.xml into English Wikipedia, which fixes most of them. Unfortunately, there are some conflicting edits that will have to be cleaned up manually (people edited after the dump export time), e.g. https://en.wikipedia.org/w/index.php?title=Template:Nothanks-sd-NPF&action=history.

I'll loop through to find these.

Ewww, XML-imported edits: https://en.wikipedia.org/wiki/Special:Contributions/Admin
:(

This is fixed. I apologize for the inconvenience.

Do you have anything more constructive than 'Ewww'? This was the simplest solution and didn't cause any issues (that goes for the username as well).

I did exactly what I said I was going to do on multiple occasions:

• rEPTR8e25d6f05b28: Import templates from English Wikipedia
• rEPTR891b3b6b5109: Add MessagePoster/Flow support to PageTriage, fix related issues
• https://phabricator.wikimedia.org/T155026#2954051

You had several days when you were familiar with this task and could easily have seen all of the above, especially the last two.

@Mattflaschen-WMF, thanks for resolving the issue. The initial issue seems to be resolved on my end now.

There were several better solutions, but it's a bit late to discuss those now.

Checked in betalabs and selectively in testwiki.

QA recommendation: Resolve.
