The error:
Dateitransfer fehlgeschlagen: Authentifizierung auf https://<site>/api.php ist fehlgeschlagen.
shows up when configured for a 1.24.1 wiki. I know that the MediaWikiApi for 1.24.1 has been changed in an unfortunate incompatible way. Since this extension is from 2011 I am wondering whether
- SSL is the problem
- 1.24.1 is the problem
or something else. How would I debug this situation?
