A subdomain is an address like blog.yourdomain.com or shop.yourdomain.com. It can host a completely separate site or a section of your main one. You can create subdomains yourself in StackCP.

Create the subdomain

  1. Log in to your FimuroHost client area at app.fimurohost.com.
  2. Go to Services and select your hosting plan.
  3. Click Login to Control Panel / StackCP. StackCP opens for that website.
  4. Open the Subdomains tool.
  5. Type the name you want in the Subdomain field, for example blog.
  6. Optionally change the Document Root (see below).
  7. Click Create Subdomain.

What the document root does

The document root is the folder the subdomain serves its files from. For example, if you have a folder public_html/support, enter public_html/support as the document root and support.yourdomain.com will show the contents of that folder.

Changes to a document root can take around 15 minutes to apply, so give it a little time before testing.

Common problems

  • Subdomain does not load: if your domain uses our nameservers (ns1.stackdns.com, ns2.stackdns.com) the DNS record is created for you. If your DNS is managed elsewhere, add an A record for the subdomain pointing to your hosting IP address.
  • Browser shows a security warning: wait for the free Let's Encrypt SSL certificate to be issued for the new subdomain, which requires the DNS to resolve first.
  • Shows the main site instead: check the document root path and wait the full 15 minutes.
