configuration file is not secure /home/mehdi/.moc/config

Hello.
Suddenly, right after configure nodm and xinitrc (I doubt it is related), moc says this.
the conf file is owned by root, though all rights are given to me. I can't change this, I don't know why so.
And it was like this before, assuredly, when it worked.
