Keys and salts disappeared

Thank you for making this great free plugin available. 5 starred and favorited. I have been using for several months on several sites and it has always worked great … Except maybe today. I was checking my wp-config file for another reason and I noticed the keys and salts were gone – just blank lines where they should be. The file date was yesterday. I manually put new keys and salts in and tested changing them with Salt Shaker and all seems to work fine. Any idea why they would have disappeared. It could be that I did something dunderheaded that has nothing to do with this plugin – but I can’t think of what that could have been.
