French formatted date in Smart Text

Hi NS Pro team
I have put the smart text "{include:articlepubdate}article_id{/include}" in my newsletter, but I get then the date in english.
I need it in french.
In Advanced Options, field "PHP Locale" I put : But it does not change anything.
Any advice ?

BTW? Nothing to do with above, but ...
​​​​​​​when I use the smart text {date} i get the date in this format : 2025-04-09
Is there any way to modify this and get something like d F Y format ? Thanks in advance...

Hello Stéphan and thank you for posting.

In the PHP Locale option, please write fr_FR. NS Pro calls the setlocale function when necessary.

To change the date format of the {date} smart text, you may create a language override of the following key:
DATE_FORMAT_LC4

Its default value is Y-m-d, but if you want something like 16/04/2025, you can write d/m/Y.

Let me know if that helps.
Thanks again.

Hi Christofer, thank you very much for your answer...
I have tried to modify DATE_FORMAT_LC4 to j F Y but the date is still Y-m-j for my {date} smart text.
And I have also set the Set Local Parameter to fr_FR (and have also tried with "fr-FR") but both keep date in english in the newsletter.
As I'm working on my local MAMP, I will wait until I instal this site on public link. So I will be able to give you an access so you will have a deeper sight ?
SO don't close this ticket too quick

Did you modify DATE_FORMAT_LC4 for the site or also for the administrator?

I have choosen "Both" when creating the langage overrides (so Admin AND Site)

Hello Stéphan.

It just occurred to me to ask: Have you got more than one languages installed on this website?
If yes, perhaps you need to add the override for the English language as well, because the scheduled task may not load the French overrides.

Can you please try and let me know?
