After reading how I managed to arrive at the wp-config.php file at the site where WordPress 4.2.2 won’t upgrade. However, clearly I there are some other steps I have to take before I can follow your instructions. Just clicking on wp-config.php and opening it gets me content removed by moderator, never post your wp-config.php file contents. Can you direct me to a site that will tell me (preferably politely) the steps I need to take to open the php file in a form I can edit it in the manner you suggested. I appreciate your help but, as you can see, I am a beginner in these matters.
