How I can modify the skin-specific styles, or interface texts

I have been working on my Miraheze Maimai Wiki, and I'm currently configuring interface visuals.

I've edited MediaWiki:Copyright-footer, but it affects all skins including Citizen which the wiki is also using. I want the content in MediaWiki:Copyright-footer to show fully on Vector 2022, but only show the license line on Citizen (hiding the additional Sega disclaimer).

How can I set skin-specific styles or footer content so they don't affect each other?

Here's an example of what I'm trying to achieve: https://ibb.co/Pvy3sSbC.

Oh, I've found the solution, THX — Chernobox (talk) 10:46, 20 September 2026 (UTC)

For posterity, the answer was to enclose the text in a span tag then hide it per skin by CSS. See https://maimai.miraheze.org/wiki/MediaWiki:Copyright-footer?action=edit and https://maimai.miraheze.org/wiki/MediaWiki:Citizen.css. Jonathan3 (talk) 20:19, 20 September 2026 (UTC)

TOPLEVELPAGE from Subpage Fun suddenly stopped working

I'm an editor on AllTheTropes.org which is part of Miraheze and on MediaWiki 1.46.0 (93bcca0).

Miraheze updated to the new version yesterday. We use Extension:Subpage Fun heavily because of the format of our wiki, and it's suddenly no longer working: it's transcluded in, among other things, our Recapfooter template, and I realized around midday today that when you save a page that includes that template, Template:TOPLEVELPAGE is coming up redlinked as Template:TOPLEVELPAGE.

I was going to edit Himouto! Umaru-chan Wiki as usual, but unable to do due to a message appear like this:

[bc3a0d5b7f9d6fc98273eb7b] 2026-09-28 15:22:50: Fatal exception of type "Wikimedia\Rdbms\DBQueryError"

I don't know where's the place of the problem, and please don't tell me that the solve is in LocalSetting.php. I only had a phone and edit the wiki with it all the time. — Quokrom (talk) 15:58, 28 September 2026 (UTC)

Updating from 1.46.0 to 1.46.1 > bug detected?

My wiki stays at 1.46.0 for the time being. No help needed. This is just a heads-up.

Fatal error in EditPage.php: Call to a member function getPage() on null during action=submit (MediaWiki 1.46.1)

Description:

After performing a fresh installation and upgrading from MediaWiki 1.46.0 to 1.46.1, editing existing pages or creating new pages fails completely. Clicking "Save changes" (action=submit) triggers a fatal exception.

Environment:

• MediaWiki Version: 1.46.1 (upgraded from 1.46.0)
• PHP Version: 8.3.33 (Running via fpm-fcgi on a shared hosting environment)
• Database: MySQL
• Extensions: None installed (Vanilla MediaWiki core configuration)
• Skins used: Vector-2022 / Timeless

Steps to reproduce:

1. Open any page or attempt to create a new page in edit mode.
2. Enter content and click on "Save changes" (or Preview, triggering action=submit).

Expected result:

The page edits should be submitted and saved to the database successfully.

Actual result:

The application crashes instantly with a fatal exception. Downgrading the core files back to 1.46.0 immediately resolves the issue using the exact same database and configuration.

Additional Notes:

The issue seems to be located within getPostMergeChecksRunner in EditPage.php on line 2521, where the page context object evaluates to null during specific background POST requests under PHP-FPM environments. ~2026-53179-49 (talk) 22:06, 2 October 2026 (UTC)
