Insecure Browser Detected
The browser version you are using is very old and insecure. Please update your browser to enable appointment scheduling.
Here's the technical explanation for your IT support:
The current Payment Card Industry Data Security Standard (PCI DSS) requires websites to support only secure communication protocols. Old browsers don't support the required cryptographic protocols designed to provide secure communications (TLSv1.1 and TLSv1.2). Your browser will get a blank page when we disable the old HTTPS protocols soon. The oldest browsers that support TLSv1.1 and TLSv1.2 secure communications are Internet Explorer 11, Edge, Chrome 22, Firefox 27, Safari 7, Android 4.4 and Opera 14. Let's keep the internet safe and your information secure.
If you're using a modern browser, then secure communication issues can be caused by BitDefender's local Root Certificate system, a kind of user-authorized man-in-the-middle (MITM) software to scan https traffic for ads, which has not been updated to use TLS 1.1 or 1.2. Many corporations use network monitoring/protection software to intercept HTTPS traffic (antiviruses, adware and NSFW filters) and have problems with the current HTTPS security standards if their software isn't up to date.
