yes. I don’t know what your exact setup is so i don’t know where exactly config.php is located for you but indeed you open config.php with your preferred editor (i use nano)
If you feel uncomfortable doing this, it may help to post your config.php in the thread. You can easily do this by going to adminstration settings and selected support from the menu on the left. There you see a button "generate system report. This will created a folder “system information” in which you will find a file named “YYYY-MM-DD.MD” you can open that and your config.php will be inside looking a bit like this:
