Check `|url=` value suggestion

The suggested IDN Conversion Tool Verisign at #Check |url== value has a limitation as mentioned Only enter the domain in the tool and not the full url. But i found another site where it is more convenient and it support for whole url, also that site has other features like url encoding/percent encoding etc. (non-promotional) punycoder. So might add that their instead of Verisign.––kemel49^{(connect)(contri)} 17:09, 6 January 2025 (UTC)[reply]

External link in |<param>= when page title really does contain a URL

What's the correct recourse for the 'External link in |<param>=' warning when citing a page whose title contains a URL for whatever reason. Is the intention that the URL be omitted or that the warning remain and generate noise?. The current suggestions are only to move the URL to a different tag (e.g. where the editor has placed it in the title field in error). DDFoster96 (talk) 21:34, 7 February 2025 (UTC)[reply]

It this a hypothetical or have you got a real-life issue? Link to it so we can all know what it is you're talking about?

Semi-protected edit request on 19 February 2025

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

The wikipedia interface to edit CSS files has the following warning when using the suggested message display snippet: Warning: Element (span.cs1-maint) is overqualified, just use .cs1-maint without element name.

Change span.cs1-maint to .cs1-maint

Change span.cs1-hidden-error to .cs1-hidden-error JamesLear314 (talk) 06:40, 19 February 2025 (UTC)[reply]

Done ~ Rusty ^meow ~ 19:34, 23 February 2025 (UTC)[reply]

@JamesLear314 and Rusty Cat: The new version without span fails to display the messages for me on Drosophila connectome in all three tested browsers so I'm reverting the edit. PrimeHunter (talk) 23:14, 27 February 2025 (UTC)[reply]

@PrimeHunter: It does not display indeed. Personally, I use

.mw-parser-output .cs1-maint, /* display Citation Style 1 maintenance messages */
.mw-parser-output .cs1-hidden-error, /* display hidden Citation Style 1 error messages */
.mw-parser-output .harv-error { /* display Module:Footnotes errors */
    display: inline !important; 
}

and it works fine (albeit with a warning about using !important), but if I remove !important the messages do not show. ~ Rusty ^meow ~ 00:14, 28 February 2025 (UTC)[reply]

Last name error

I'm seeing an error message because an author has the last name of bureau:

Davies, Roger L.; Kuntschner, Harald; Emsellem, Eric; Bacon, R.; Bureau, M.; Carollo, C. Marcella; Copin, Y.; Miller, Bryan W.; Monnet, G.; Peletier, Reynier F.; Verolme, E. K.; de Zeeuw, P. Tim (February 2001). "Galaxy Mapping with the SAURON Integral-Field Spectrograph: The Star Formation History of NGC 4365". The Astrophysical Journal. 548 (1): L33 – L36. arXiv:astro-ph/0011254. Bibcode:2001ApJ...548L..33D. doi:10.1086/318930. {{cite journal}}: |last5= has generic name (help)

Is there a work-around? – Praemonitus (talk) 16:19, 14 March 2025 (UTC)[reply]

—Trappist the monk (talk) 16:23, 14 March 2025 (UTC)[reply]

Oh okay. I just found I could use a Unicode character to remediate it, but your approach is probably more kosher. Thanks. Praemonitus (talk) 16:28, 14 March 2025 (UTC)[reply]

ISBN checksum error

Hi everyone!

Recently, on ICD-11, I cited this book.

The page lists three ISBNs for it:

9789290612487 (‎PDF)‎
9789290612483 (‎Paperback)‎
9789290613053 (‎Hardbound)‎

I linked to the ebook, so I figured I had to use the first one, the PDF ISBN. However, when I copy-pasted it into Cite book, this happened:

WHO Western Pacific Region (2007). WHO International Standard Terminologies on Traditional Medicine in the Western Pacific Region. ISBN 9789290612487. {{cite book}}: Check |isbn= value: checksum (help)

This checksum error does not occur with the other two ISBNs.

Did the WHO use an erroneous ISBN here? Or is this a mistake on the Wikipedia side?

- Manifestation (talk) 17:03, 11 April 2025 (UTC)[reply]

Your paperback and pdf isbns are identical except for the checksum. The '7' checksum appears to be correct for the 10-digit form:

{{isbn|9290612487}} → ISBN 9290612487

looks to me like WHO incorrectly stated the ISBN as ISBN 978 92 9061 248 7 Parameter error in {{ISBN}}: checksum on the reverse of the title page.

You can remove the 978 prefix and write |isbn=92-9061-248-7 or you can write |isbn=((978-92-9061-248-7)) which will suppress the error message and add the article to Category:CS1 maint: ignored ISBN errors.

—Trappist the monk (talk) 18:01, 11 April 2025 (UTC)[reply]

Ok thanks! I've used the 10-digit number, which seems to be recognized by all the big sites (e.g. Google, Worldcat).

Btw... I don't think the template should throw a maintenance message when a misprinted ISBN is used with "(())". A maintenance message implies that something needs to be maintained, i.e. fixed. But if a printed book uses an incorrect ISBN, and if that book was never re-printed with the correct ISBN, then us Wikipedians have nothing to fix.

Instead of this maint. category, perhaps there should just be a category called Category:Articles citing books with incorrect ISBNs, emphasizing that these erroneous ISBNs are not to be fixed. At least not by us. Cheers, Manifestation (talk) 19:33, 12 April 2025 (UTC)[reply]

The category specifically says that it is a tracking category and not an error category. If you have better wording for the category than This is not an error category and pages in this category should be "fixed" only if the special markup has been misused, please suggest it or be bold and edit the category page. – Jonesey95 (talk) 18:56, 16 April 2025 (UTC)[reply]

Every category is used to track. A maintenance category implies that something needs to be maintained or fixed. In this case, there is nothing to fix. Cheers, Manifestation (talk) 20:58, 16 April 2025 (UTC)[reply]

I agree. Inspection is part of maintenance, and does not always result in finding of errors that need fixing. – Jonesey95 (talk) 17:15, 18 April 2025 (UTC)[reply]
