I am using WordPress Multisite for my blogs. I have around 5-6 blogs installed with 3 blogs using the same theme. Now, I want to edit a .php file in theme, so as to show custom fields using the_meta() only on one of these 3 blogs.
Where I should make changes so that changes are applicable on one blog only and not other 2 blogs.
I am not able to see Editor link under Appearance.
