Domain
Only an owner or admin can change anything on this screen. Changes to the slug, production URL and URL style take effect when you choose Save.
Space Slug
Section titled “Space Slug”The part before .customers.rubikc.com in your Rubikc address. Lowercase
letters, numbers and hyphens.
Production URL
Section titled “Production URL”The address search engines and shared links use for your storefront — in page links, the sitemap, and search listings. It does not decide where your storefront answers: a custom domain serves your storefront as soon as it is Active, whatever this is set to.
| Option | Uses |
|---|---|
| Use slug | Your <slug>.customers.rubikc.com address |
| Use your custom domain | Your custom domain. Available once a domain is Active. |
| Manual | An address you enter |
Once your custom domain is active, switch to Use your custom domain so search engines index that address rather than the Rubikc one.
URL style
Section titled “URL style”How the addresses of your cubes are shaped.
| Option | Addresses look like |
|---|---|
| Shopify paths | /products/my-product, /blogs/news/my-post, /pages/about-us or /cubes/my-page, the same as a Shopify store |
| Any path | Any path, such as /my-post or /2026/06/my-post. Use it for a site that came from WordPress. |
Pick the style your old site used, so its links keep working when your domain points at Rubikc. Connecting WordPress to a Space with no cubes yet switches it to Any path.
With Any path, an address cannot start with a part the storefront uses
itself, such as /cart or /collections, or with two or three letters such as
/art/, which read as a language. You can switch back to Shopify paths only
once every cube address fits that style.
Custom Domains
Section titled “Custom Domains”Add a domain here, as a subdomain such as www.yourstore.com, in Hostname.
For the bare domain, add the www version and
redirect the bare domain to it. Remove takes a
domain off the Space.
Each domain in the list shows:
| Status | Overall state of the domain |
| SSL status | Whether a certificate has been issued — separate from DNS, and follows it |
| Last checked | When Rubikc last looked |
| Verification errors | The specific failure, when there is one |
DNS records
Section titled “DNS records”Each domain shows the three records it needs, with copy buttons and an individual status:
- Hostname CNAME — points the domain at
saas.rubikc.net - Domain ownership TXT — proves the domain is yours
- Certificate validation CNAME — issues and renews the certificate
Records 2 and 3 appear as soon as their details are available, often right after you add the domain. While this screen is open it re-checks a pending domain on its own. If a record says its details are not available yet, Check fetches them.
A www domain also shows a fourth, optional step: the A record that
redirects the bare domain to it.
Per-record status is Not checked, Matches, Wrong value, Not found, or Lookup error.
Looks up your records from Cloudflare and Rubikc’s DNS servers, and fetches the ownership and certificate details if they are not already shown.
