Resolve "Site Not Secure" Warning

Visitors who open [login to view URL] in Google Chrome are greeted with the red “Site not secure” warning page. I have not touched the hosting, DNS records, or SSL certificates recently—only routine WordPress core/plugin updates—yet the alert suddenly appeared. I need you to: • trace the exact reason Chrome is flagging the site (expired or mis-issued certificate, mixed-content call, HSTS conflict, or anything else); • implement the fix so every URL (www and non-www, http and https) loads cleanly without security warnings; • keep our current WordPress setup, content, and design intact. Acceptance criteria 1. [login to view URL] and all internal pages open in Chrome with the standard padlock, no “Site not secure” or equivalent interstitial. 2. SSL Labs or a similar public checker reports the certificate chain as trusted and up-to-date. 3. A brief summary of the root cause and steps you took so I can document the change. Access to cPanel, WordPress admin, and the current certificate panel will be provided on approval.
