I am on this page: http://www.tipsandtricks-hq.com/wordpress-affiliate/how-to-changecustomize-the-url-of-the-affiliate-view-42
I would like to use Method #1. I understand the first 2 steps, but don't know where EXACTLY TO upload the index.php after I have modified it with my domain name. Which folder does it go in? Wp-content? And which folder within Wp-content. Or does it go in the Wp-Admin folder? Please help. THanks a lot.
