When trying to post in my ISP newsgroups, two error boxes appear and nothing is posted : 

- "Error - KNode" Unable to load/save configuration. Wrong permissions on home folder? You should close KNode now to avoid data loss.

=> To be sure it wasn't a permission problem I chown'd all my home directory files.

- "Errors occurred while sending these articles: The unsent articles are stored in the "Outbox" folder." and the title of my article.

=> Nothing in the Outbox folder.

I deleted share/config/knoderc and share/apps/knode/ and re-created the account => same problem.

If launched from a console :
