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 .
If you click "Veire l'Istoric" (See History) at the upper right tab of the same page, you will find the same thing.
Thank you for your time.
