It is unmaintained and completely broken on 1.38 (nothing appears whatsoever)
|T9446 Upgrade to MediaWiki 1.39.1
|T8982 Migrate revision_actor_temp usage back to the revision table
|T8743 Upgrade to MediaWiki 1.38.1
|T9340 Remove Skin:Pivot
A patch has been submitted for this skin and confirmed as working (though not yet merged), can it please be retested for those wikis that use it?
To be clear, I understand the maker is likely going to stop and has stopped maintaining this skin… this however gives us one more update cycle to modify the CSS for another skin to make the switch, rather than being in a panic to do it all right now and see what else doesn’t work or needs changing after the upgrade.
Sorry, I'm not a programmer, just a MH user. I saw there was a fork by a Wikimedia developer, with one file different (which has 4 lines changed in it. isLoggedIn looks to have been changed to isRegistered in each). I didn't realize it was a problem to swap out that file or use fork at the bottom of the link, so again, sorry.
We were waiting for the upgrade to 1.38 to hopefully make the switch to MH feasible, we'll wait.
It becomes hard when every extension needs forks deploying, that are all on branches that could be deleted at any point and if a change is made upstream and not pulled to the deployed branch. It's on us to notice and work out the right solution.
I personally find "It is unmaintained" simply false given that after the initial ticket for it a patch was submitted within 3 days.
I hope once it is merged into the trunk again, this ticket will re-evaluated and we can keep our favorite theme for a while still.
This extension has been moved to Wikimedia Phabricator, is marked as maintained (now maintained by Wikimedia folks, as was kindly offered here once it was posted about), and is now marked compatible with 1.39+ on its extension page.
I've created a new ticket to request it get re-enabled (and cross referenced this one).
