Why am I getting "This webpage has a redirect loop"

I've set up my very first multi site...

http://loweralabama.biz/

Everything seemed to be going fine until I tested creating a new site.

When I try to edit the new site at

http://loweralabama.biz/testnewmu/wp-admin

I get the following error:

This webpage has a redirect loop

The webpage at http://loweralabama.biz/testnewmu/wp-admin/ has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

I tried doing some research and tried a couple of things but I think I am out of my depth now :slight_frown:

One of the things I did read about was that maybe it was a GoDaddy issue. My site is hosted at GoDaddy and is aliased to my main domain if that could be an issue?

Has anyone had any success in creating a multi-site on Godaddy? I understand there may also be issues with using multiple databases?

Any guidance would be much appreciated, even if it is just a recommendation for a host that is guaranteed to work out of the box!
