I have two websites. I used one to develop a custom post template that would display site admin profile information, including custom fields I have added to the profile page.
I have transferred the fully developed template to the live site and was preparing to deploy, when I discovered that the PHP code did not work on the live site.
Both sites are WP 3.4.2 Multisite Networks. The only difference is that the development network only has the one main site, no subdomains. The live network has multiple subdomains, and the template was tested on one of the subdomains when it was discovered that the code did not work in the new environment.
Here is a sample of the code I am using to display meta information from the site admin user profile:
