When the name changes, the lock changes too

A certificate written for the old name does not fit the new name.

Write the new name onto the certificate, then point the old name at the new one. Do not leave both empty for a day.

What it is for A certificate has an end date too. When it ends, the lock drops and the page warns. Renewal sits inside the hosting account.

How it sits A certificate works for the domain it was written for. It does not clip onto another name. A subdomain must be named on the certificate too.

Where it breaks When the name changes, the lock changes too. SSL is the lock in the browser. The address opens with https. On a page without the lock the visitor sees a warning and leaves the form.

What to do A certificate binds to the domain it was written for. Payment ends on the Stripe page. The card number does not sit on this site.
