So you want to disable "hide" for unregistered?

When no description in my language is available it uses the Wikidata's convention to add language name next to the label when another language (en) is selected. It is displayed incorrectly: language name is part of label link and without space between name.

@Magalia, tell what you need.

You can only merge revisions from "older" page to "newer". "Newer" is based on first revision (I suppose). So, you need... merge some revisions from the "valid" page to the "orphaned" page and then do second merge to move all again to the valid title.

Done

For "tytuł", Polish Wikipedia editors can edit the templateData to add a "title" alias that help the tool to know they are equivalent.

Yes, it happens also on me.

Could you confirm it changed?

Can you give more details on what needs to be done?

Entries about these pages (linked in categorylinks) should not exists because these pages were removed from this category. So MediaWiki code for categorylinks update not always working after decategorisation.

Also szl, test

This new form (often unused) makes longer page to scroll to actual list. And tag input is too wide ;), and still primitive. Are non-horizontal forms standard now? Where to discuss this change?

This was gadget issue, report locally.

Misunderstanding. This disabled the whole feature. We asked to have two tabs by default for not logged in. Users can't now set SET in their preferences.

Sadly, the premise of this discussion is incorrect. If an editor comes back after a long hiatus (specifically, from before 1 March 2016), and tries to edit, a dialogue is shown asking them which editing mode they want, and an "Always give me the wikitext editor" option is prominent.

Problem is VisualEditor is loaded first, taking a while, and then dialog is shown.

I am sure this is the reason: https://github.com/wikimedia/mediawiki-extensions-Cite/commit/351a08d1b79d7817c634597178dc35a49239a741

Other wiki has this issue too. Is it intentional?

Why would somebody use an underscore instead of the actual name?

I think it is because some translations are marked as "FUZZY" because of "Namespace changed from the definition". Try to confirm it and wait for next update.

And are visible in deleted contributions of deletor. Is this intentional?

And also - deleted posts are visible in... your deleted contributions!

Make sure you have enabled both NWE and CodeMirror and CodeMirror is activated completely (colors on new editor or activate in normal editor before).

1. Enter recentchanges
2. Choose namespace(s) to filter
3. Click exclude button
4. It should exclude selected namespaces - it works
5. Now save whole set
6. Enter to RC again
7. Load saved filter
8. Notice selected namespaces are not excluded but included. Can't see "not" word on buttons in Active filters and on results it shows only from selected namespaces instead "from all excluding selected".

Maybe only me?

And when you enter on Recentchanges page and load saved setting you still have "not" options to them? It saves only namespaces but "not" is not assigned.

Also checkboxes on the left side of names.

The same reason is for collapsing checkbox in ERI filters?

No, it needs one move.

I found it can be partly achieved by moving one (for example left) after the second pointer.

This is good function. But if someone thinks not - maybe adding button like in external editors to show/hide markings for non-visible elements like tabs, newlines?

form-rights2 too...

Wsa-form-intro-faq has bad link - double colon.

Per T153987

Ok, this was adblock issue.
