I purchased a renewal certificate after I got a renewal notification, but the certificate was not renewed and I got another renewal notice
If a renewal certificate is ordered, but you still receive Renewal Notifications, most likely the ordered certificate has Newrenewal status now.
SSL Certificates are not renewed automatically as domain names are. The certificate expiration date is established on Certificate Authority’s side and encoded in the certificate’s body, therefore it cannot be changed. To renew the certificate, a renewal one needs to be activated, issued and installed on the server.
In order to start renewal activation, log in to your Namecheap account >> hover the mouse over your username in the left-top corner >> click on Dashboard >> click on Domain list on the left side of the account area >> locate the domain name, to which the SSL certificate is issued >> click on the caret to expand the list of products and services, assigned to the domain name >> find the purchased renewal certificate and click on Activate button to proceed with the activation.
On our site you will be requested to perform steps similar to original activation. Eventually you will receive a renewal certificate that should be installed on the server instead of the expired one.
