@toolboxwebdesign, thank you very much for your answers. You really helped me with this.
One more question: which file/template do I have to change when I want to display the added fields under the title of a post? I am using the standard template in WordPress 4.1.1 theme ‘Twenty Fifteen’.
Thanks! Do I need to search for the Home Page via FTP and then to place the code via FTP?
Where can I place this code? (Sorry, I don’t have experience with this.)
