[problem] adding scuttle sites to auto social poster

I tried to add scuttle sites to auto social poster but I get the folowing message :

scuttle

username: *******
status: Error while posting. Post failed.

scuttle
(drrlibrary.org
username: *****
status: Login error. Post failed.

scuttlePLUS

Did someone managed to add scuttles to social bookmark?
I hope someone can help me out!
