Popups in MediaWiki private server?

When linking a wikipedia article to my article, does it recognize it as part of the MediaWiki group and generate a pop up or this is exclusive to server-side content? Eduard da Silva (talk) 23:43, 3 February 2025 (UTC)

Workaround - Handling lack of popups on 1.43 when logged in

For some reason, the code added to extension.json doesn't work.

So, go to your extensions/Popups/extension.json file at around line 173 and edit out:

	"ConditionalUserOptions": {
		"popups": [
			[
				"1",
				[
					"registered-after",
					"20170816000000"
				]
			],
			[
				"0",
				[
					"named-user"
				]
			]
		]
	},

Get rid of the array next to

"popups":

and change to

"popups": "1"

like so

    "ConditionalUserOptions": {
		"popups": "1" 
	},

Save the file.

Visit a page on your wiki that should have popups. You may need to do a hard refresh to purge cache, but it should work after this. Joe Beaudoin Jr. Redux (talk) 21:54, 5 March 2025 (UTC)

I didn't need to do this. What I did need to do was to go to my user Preferences > Appearance and check the box, "Enable page previews (get quick previews of a topic while reading a page)". Fanra (talk) 06:53, 16 March 2025 (UTC)

Interesting! This may be something that affects wikis with far older content (in excess of a decade). Good to know in any event. Thank you! Joe Beaudoin Jr. Redux (talk) 17:45, 25 May 2025 (UTC)

Page should be updated with instructions for enabling the previews by default for existing users

I enabled this extension yesterday and found that it does not automatically enable the feature for existing accounts. After going into IRC, I was told that I should add the following line to my config:

$wgConditionalUserOptions['popups'] = [];

This enabled it for existing users. Apparently this is new behavior as of 1.42, so the page could use updating with this information. I would edit it myself, but I don't understand the translation source format and don't want to break it.JFolvarcik (talk) 18:32, 16 July 2025 (UTC)

Show thumbnails out of whitelisted categorys

Hello,

is there a possability to show thumbnails in popups from categorys, when only the category is whitelisted?

$wgWhitelistRead = [

    'Kategorie:Bücher',

    ];

That just creates a popup that tells, that there is a problem with the preview. ~2025-38560-7 (talk) 09:27, 14 August 2025 (UTC)

It also returns the section as a link

On Wikipedia; I search for <pre>using only ingenuity and minimal resources</pre> and get search results. The sixth item down looks like <pre>Ngano (Tshivenda narrative song) (section Etymology and definition)</pre>. This uses Extension:Page Preview. It returns the page as a link. It also returns the section as a link.

How can I achieve this wonderful functionality in a local wiki?
