Hello, first post here. I am glad to see this is a very active community and hope to get this issue resolved.
First, I would like to say I have followed through this PDF: http://wpebooks.com/wp-content/uploads/downloads/2011/08/CreateAWordPressNetwork.pdf
I complete every task until I come to the Login again section. I attempt to login which directs me to a page with my theme (I use Gleam theme from Elegant Themes) with the words "Registration has been disabled."
Note: My Gleam theme's coding also looks a bit broken as well when I surf through the site pages.
Am I missing anything important? Do I have to upgrade my hosting (hosting info below)?
I have attempted the following fixes (with no success):
1. .htaccess and Mod Rewrite & the Switching network types - http://codex.wordpress.org/Multisite_Network_Administration#Network_Admin_Link_Location
2. I've taken out the "www" in the wp-config.php file with a blank theme'd page.
Currently, I have put everything back to normal on the back end.
I have a GoDaddy domain account with "A @ 184.108.40.206" set in the domain control panel.
GoDaddy hosting plan with "Hosting - Web - Deluxe - Linux" package.
I use FileZilla to edit my FTP files.
