Hello,
Wikipedia in Occitan has a bug with displaying dates, where the wrong form is used to display the last-modified date. Other Wikimedia projects (checked Wiktionary, Wikimedia Commons) display dates correctly.
Go to https://oc.wikipedia.org/wiki/Acu%C3%A8lh on any web browser.
Scroll to the bottom of the page.
Read the fourth line from the bottom where it displays the last date modified: "Aquesta pagina es estada modificada pel darrièr còp lo ..."
Actual Results: What the application did after performing the above steps.
The "Long month name" is used instead of the "Genitive month name", so a "de" is missing before the month (in this case, "mai").
"Aquesta pagina es estada modificada pel darrièr còp lo 28 mai de 2020 a 20.49." at https://oc.wikipedia.org/wiki/Acu%C3%A8lh .
Expected Results:
The Genitive month name is displayed, and therefore the text appears as "Aquesta pagina es estada modificada pel darrièr còp lo 28 de mai de 2020 a 20.49."
For an example of it working correctly, see the third line from the bottom at Wiktionary: https://oc.wiktionary.org/wiki/Wikiccionari:Pagina_d%27acu%C3%A8lh .
Additionally:
If you click "Veire l'Istoric" (See History) at the upper right tab of the same page, you will find the same display issue in those dates. You can again compare it to the Wiktionary page's history, where it works correctly.
Thank you for your time.
