SVN can't checkin

I’m unable to update my plugin. I’ve reset my password via the web, and verified that the capitization, etc. of my user name is correct. I’ve also deleted ~/.subversion/ Nonetheless, I get an error.

svn –username [email protected] –password xxx ci -m ‘fix readme’
svn: Commit failed (details follow):
