I was trying to follow through WPML tutorial to set up language subdomains. However, Siteground doesn't offer cPanel in their hosting service. They use something called "site tools". When I create a subdomain, a new public_html folder under that subdomain will be automatically created. I was unable to point language subdomains such as de.pioneersnonpareil.com to my main public_html folder because Siteground doesn't offer any domain tools for that.
Siteground support wrote back with a solution using symbolic links as such but they would like me to double check with you guys:
1. Create subdomains using SiteTools (when one does that, the url folders are created under /www/); issue new SSL certificates for them if necessary
2. Go to each language url folder (fr.yoursite.com) under /www/ which was created by Siteground's SiteTools when subdomain was generated, and delete the public_html folder.
3. run this command via command line for each and every language to be added:
