ERR_TOO_MANY_REDIRECTS error

I’ve got the same problem… but I am not clear on the fix. Can you elaborate?

What needs to be changed to what?

I have:

domain.com
second.domain.com

and www should be just an alias for domain.com - it was correctly redirecting from www.domain.com to domain.com.

Post installation, all have an infinite redirect loop.

Thanks.
