Depending on your browser, if you Select/Copy the config file lines posted by above, you may encounter blank spaces at the beginning of each line. When you paste those into your text editor, you may not realize that your lines all start with a space. YOU MUST REMOVE LEADING SPACES!
The .ini file parser used in Unreal is apparently either intolerant or pedantic of leading space characters on the left (key) side of .ini file lines, so this will cause your .ini file entries to have no effect.
Note to Unreal’s forum moderators: could you perhaps implement a little “Copy to Clipboard” button that appears above and below any blocks of code posted on the Unreal ? It would alleviate the above problem.
