I’m trying to create a multisite with subdomains for different languages for an already created web.
In General options my url was http://www.centrocalima.com and I changed it to centrocalima.com. I have seen that in the host is also well defined.
I created a subdomain wildcard too.
I follow all the steps that tells me about wordpress wp-config and htaccess but when I try to enter the page tells me that there has been a redirect loop. I tried a thousand things but can not get it to work.
That’s not a free hosted WordPress.com blog and we cannot help you here. Your question is about a self-hosted WordPress blog and you’ll find help at the WordPress.org forums. http://wordpress.org/support/
