This is also affecting the Vietnamese Wikibooks. Contrary to the table in T290091, rOMWCbf82bfb3ddcaff04a1e90abc435ccb26f792780c uploaded only a single en-wordmark.svg and used it for the French Wikiquote, Vietnamese Wikibooks, Outreach, and Strategy wikis.

This affects the logo at the top of every page at the Vietnamese Wikibooks, either when using the mobile interface or when using the new Vector skin. It’s very confusing for readers to see the site branded with another site’s wordmark.

What's wrong with the logos for outreach wiki ?

What should the right logo be?

It was showing "Wikiquote" until recently. That part appears fixed now. :)

So is the issue just with Vietnamese Wikibooks? If so, I've moved T290091 into needs more work as that task hadn't been QAed yet. I think we can close out this ticket?

And strategy-wiki. Those are the only reported problems, so yes, merge as needed. :)

Config patch 748214 (which is linked to original ticket T290091) fixes this for Vietnamese Wikibooks and Strategy Wiki.

Thanks for the report!
