--- Comment #7 from Malafaya malafaya@clix.pt --- Got it:
https://no.wiktionary.org/w/api.php?action=query&prop=info&format=xm...
returns results (just 50...) but also:
<warnings> <query xml:space="preserve">Too many values supplied for parameter 'titles': the limit is 50</query> </warnings>
Default query value in pywiki is 60... Setting it to 50 or lower (-query:50) should do the trick. This is probably some new change to the API.
