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.

MOC will refuse to start if [the configuration file] is not owned by either root or the current user, or if it is writable by anyone other than its owner.

The conf file is owned by root, though all rights are given to me.

Does this explain your problem?

If not, please post the output of: ls -l /home/mehdi/.moc/config
