Today, I moved an installation of WordPress to a new domain (from the .com version to the .org version) using these instructions: http://codex.wordpress.org/Moving_WordPress (the first set)
I changed the WordPress & Blog Location URIs, downloaded the files, and reuploaded them to the new directory. When I go to the new location (http://redletterchristianresources.org/), a file containing the contents WordPress's index.php file downloads automatically.
What did I do wrong? / What do I need to do?
