Can you please provide logins and example links to private boards, then I can check account support. Send them to
support@jdownloader.org
Also it would be good to provide debug logs. Enable Settings-Advanced Settings-Log.debugmodeenabled and restart JDownloader.
Now try again and after error, create a log, see
https://support.jdownloader.org/Know...d-session-logs
and post shown logID here
Nothing has changed in pinterest plugin. Do you mean by *sub boards* the /fashion link that worked fine for me or do you mean something else?
