I'm an Oversighter (OS) on fr-wp ([[ https://fr.wikipedia.org/wiki/Sp%C3%A9cial:Liste_des_utilisateurs/suppress | check ]]). We used to access suppression logs on [[Special:Log/suppress]] (or [[Spécial:Journal/suppress]] in French); this is the link used both [[ https://en.wikipedia.org/wiki/Wikipedia:Oversight#Logging | on en-wp ]] and [[ https://fr.wikipedia.org/wiki/Wikip%C3%A9dia:Masqueur_de_modifications | fr-wp ]] pages about OS. On fr-wp, it gives the URL https://fr.wikipedia.org/wiki/Sp%C3%A9cial:Journal/suppress. But this URL doesn't work anymore. When using this link, I get the two following error messages, and no log at all is displayed:
- "Des problèmes sont survenus avec certaines de vos valeurs."
- "La valeur que vous avez spécifiée n’est pas une option valide."
Note: I accidentally found that when adding `?uselang=qqx` at the end of the URL (https://fr.wikipedia.org/wiki/Sp%C3%A9cial:Journal/suppress?uselang=qqx) to see mediawiki interface messages titles, the log displayed correctly.
(I obviously can't produce screenshots.)
