Due to unknown changes in API centralauthtoken doesn't work anymore at all. Previously the following schema worked:
- obtain centralauthtoken from local wiki (for example https://ru.wikipedia.org/w/api.php?action=centralauthtoken )
- do anything on another wiki (for example https://www.wikidata.org/w/api.php?centralauthtoken=%YOURTOKENHERE%&action=query&meta=tokens&type=csrf )
Currently second point results in error message:
"error": { "code": "badtoken", "info": "The centralauthtoken is not valid", "*": "See https://www.wikidata.org/w/api.php for API usage" }
This breaks all interwiki wikidata editing gadgets (aka WE-Framework gadgets) used on different wikis
