Fix SSL Warning on Website

Visitors to melbournehousesitters.com.au are being greeted by an “dangerous site” alert, and it’s driving them away before they even see the content. I have not touched the code or updated anything recently, so the problem is likely server-side or certificate-related. I’m also not certain whether an SSL certificate is currently installed, active, or expired.

I need someone to diagnose the exact cause of the browser warning and restore a fully secure padlock on all pages. That may involve confirming or installing a valid SSL/TLS certificate, correcting any mixed-content links, and making the necessary server or DNS adjustments so every request is forced to HTTPS without errors.

Deliverables I will use to sign-off the job:
• A valid, trusted certificate properly configured for melbournehousesitters.com.au and any www/non-www variants
• No “Unsecured” or similar warnings in Chrome, Edge, Safari, Firefox on both desktop and mobile
• A brief summary of the steps you took so I understand what was fixed and how to keep it secure going forward

Once completed, the site should load cleanly and confidently for every visitor.
