IDK Why? --Liuxinyu970226 (talk) 00:25, 28 October 2018 (UTC)[reply]

agreed, I removed the claim. ArthurPSmith (talk) 18:14, 29 October 2018 (UTC)[reply]

References

[edit]

Why do statements with this property need a reference? The link goes to CentralAuth, so it can be easily checked if the Wikimedia username belongs to the item. Esteban16 (talk) 02:33, 6 February 2019 (UTC)[reply]

Entries with space didn't work

[edit]

This property is replacing the space " " by a "+" sign, so every entry with a space in it isn't working (click on the examples about Jimbo and Magnus and you'll see). Simon Villeneuve (talk) 14:36, 12 December 2019 (UTC)[reply]

@Simon Villeneuve: Huh? The examples work for me??? Maybe you have a javascript gadget that's messing up the links? ArthurPSmith (talk) 15:03, 12 December 2019 (UTC)[reply]
Strange. I've try unconnected on another browser (Chrome, the first one is Firefox) and I have the same problem. Simon Villeneuve (talk) 15:06, 12 December 2019 (UTC)[reply]
@Simon Villeneuve: Oh wait, I spoke too soon - the links in the examples on this talk page work fine, with a "%20" for the space character, but the links in the examples on the main property page do not (with a '+' for the space) as you said. Did something recently change in the Wikidata UI translation of space characters in formatter URL's? ArthurPSmith (talk) 15:16, 12 December 2019 (UTC)[reply]

Sample: Jürgen Cieslak (Q19287397). Conny (talk) 16:51, 2 January 2020 (UTC).[reply]

Is it possible to fix that? Regards, Conny (talk) 06:02, 10 February 2020 (UTC). So the sample works: [1] . Conny (talk) 06:03, 10 February 2020 (UTC).[reply]

Is there an user with the experience to fix that? Regards, Conny (talk) 17:28, 8 April 2020 (UTC).[reply]

Wikimedia username:

[edit]

I'm adding "Wikimedia username:" to my work here. I then get a "!" where it's stated "citation needed constraint" and that I need to add a reference.
I have read and tried numerous variations of https://commons.wikimedia.org/wiki/User:Goran_tek-en but no one has been accepted.
What am I supposed to put there?Goran tek-en (talk) 12:33, 15 July 2021 (UTC)[reply]
