How do I place code (required when subscribing to Feedburner)into my blog’s Source Code file. It is for the “Tiga” theme. I was told that in order to “modify” the Source code file I would need to have knowledge of php script programming language because WordPress and the “Tiga” theme are using php language.
No, you cannot do that!
You have two options:
a) edit the theme files online – logging in to your admin panel > Presentation > Theme Editor… but I never recommend that
b) editing the theme file(s) on your computer in a plain text editor and uploading the modified file(s). Always make a backup copy before modifying any file!
