I started with a fresh install of WordPress through GoDaddy's application install. Everything was working fine. I then followed the directions to a T from WordPress to upgrade to multisite. I've done this a ton of times before with no problem. When I finish and go to log back in, I enter my PW and am redirected to the login screen again.
I've done this three times with the same result.
If I upload the old config file, I can log in with no problem. Once I upload the multisite config we get the loop.
I called Godaddy and they said everything checks out on their end. They said that WordPress is installed correctly. Again, it's a fresh install and I didn't see any problems.
But this may be where the problems are. I installed this WP on a subfolder (domain.com/newsite). I then redirected a domain name to this subfolder. No problems though as the new install worked and the domain redirected with no problem. When I go to updgrade, it walks me through the necessary steps and I am able to install subfolder option instead of subdomain.
