How to Fix “Not Secure” SSL Warning on Chrome (Complete 2026 Guide)

How to Fix the “Not Secure” SSL Warning on Chrome (Complete 2026 Guide)

If your website shows a “Not Secure” warning on Chrome, customers instantly lose trust — especially if your business takes bookings, inquiries, appointments, or payments.

Google now marks all HTTP websites as insecure, even if there is no payment form.

With rising cyber frauds in India, customers expect one simple thing:

A secure HTTPS padlock icon.

🚫 What Causes the “Not Secure” Warning?

There are three major reasons:

1. SSL Certificate is Missing

Your website is running on HTTP instead of HTTPS.

2. SSL Installed but Not Configured

Website loads on both HTTP and HTTPS — causing security downgrade + duplicate content issues.

3. Mixed Content Errors

Your page loads through HTTPS but images/scripts/css load through HTTP.

This is extremely common in WordPress sites.

⚠ Why This Warning is a Serious Problem

If ignored, businesses face:

  • Customer trust loss
  • SEO ranking drops
  • Payment gateway failure
  • Browser blocks
  • Data exposure risk
  • Email issues (SMTP/DMARC)

Chrome, Firefox and even Safari now inform users when forms are insecure — causing lead drop and sales collapse.

🧩 How to Fix “Not Secure” Warning (Step-by-Step)

Here is the full breakdown:

🔹 Step 1: Install an SSL Certificate

If hosting offers Let’s Encrypt:

  • cPanel: Security → SSL/TLS → Run AutoSSL
  • Plesk: Certificates → Let’s Encrypt
  • DirectAdmin: SSL Certificates → Free & Paid → Let’s Encrypt
  • Cloudflare: SSL/TLS → Flexible / Full Mode

If not, buy from:

  • Sectigo
  • DigiCert
  • RapidSSL
  • GeoTrust

🔹 Step 2: Force HTTPS Redirect

After installation, force redirect all HTTP to HTTPS.

For Apache (.htaccess):

RewriteEngine On RewriteCond %{HTTPS} !=on RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

For Nginx:

return 301 https://$host$request_uri;

For Cloudflare:

  • Enable Always Use HTTPS
  • Enable HSTS

🔹 Step 3: Fix Mixed Content Errors

Mixed content occurs when page is HTTPS but resources load via HTTP.

Check errors using:

  • Chrome DevTools → Console

Fix Options:

  • WordPress: Really Simple SSL
  • Database: Search & Replace HTTP → HTTPS
  • CDN: Enforce HTTPS

🔹 Step 4: Fix SMTP & Email SSL

Most business owners ignore email SSL. That causes:

  • Emails landing in SPAM
  • DMARC failures
  • Lead loss

🔹 Step 5: Check Google Blacklist

Google Safe Browsing Report
  • If status = Unsafe → Malware cleanup needed

🛑 Do Not DIY If You Have:

  • Payment Gateway
  • Booking Forms
  • Medical/Student Data
  • Real Estate CRM
  • Custom PHP Backend
  • SMTP Integration

Wrong configurations cause:

  • Email outages
  • Blacklisting
  • Payment failures
  • Hosting suspension
  • Traffic loss
  • SSL infinite loop
