I need a fresh single-domain SSL certificate installed and fully activated on my site. Nothing else on the server has changed recently, so this should be a straightforward update: replace the expiring cert, confirm the chain is correct, and make sure all pages load over HTTPS without warnings. Please handle the CSR, installation and any required redirects or mixed-content fixes, then give me a quick rundown of the steps you took so I can keep the records on file. I’ll supply any host or registrar credentials you need as soon as we start.
