An SSL (Secure Sockets Layer) certificate is no longer optional for your WordPress site; it is a critical requirement for security, SEO, and user trust. Here’s why you may need to convert to HTTPS if you haven’t by now:

1. Google’s HTTPS Requirement & SEO Impact

Google has made sure to prioritize HTTPS sites over HTTP sites because they are more secure.

SEO Benefit: Switching to HTTPS can boost rankings, especially for highly competitive keywords.

2. Security Benefits: Protect Your Site and Users

SSL encrypts all data between your WordPress site and visitors. This means an SSL-protected site is preventing:

3. User Trust & Higher Conversions

An SSL certificate stops browser “Not Secure” warnings and helps to increase visitor trust in your website. Beyond conversions, SSL delivers financial benefits through advertising. Google Ads prioritizes HTTPS sites with higher Quality Scores. Non-SSL sites can experience reduced cost-per-click (CPC) and ad visibility.

Key Takeaway:

Troubleshooting Common SSL Issues

A WordPress SSL certificate is important for website security, but it can sometimes cause technical issues that prevent your site from functioning correctly. Here are detailed solutions for the most common SSL problems you may face:

1. Mixed Content Errors (Broken Padlock Warnings)

Mixed content occurs when your WordPress site loads over HTTPS, yet some resources (images, scripts, stylesheets) are still being loaded via uncertain HTTP connections. This triggers browser security warnings and breaks the padlock icon.

How to Fix Mixed Content Errors

Therefore, with the following simple manual and plugin settings, you can troubleshoot the mixed content error easily. 

Plugin Solutions (Recommended for Beginners)

Let’s go through some of the plugins that can troubleshoot the WordPress SSL certificate errors for you: 

  1. Really Simple SSL plugin automatically detects and fixes mixed content and specifically targets mixed content issues.

Manual Fixes (For Advanced Users)

Here are some manually performed fixes you can implement as an advanced user:

  1. Database Search & Replace: Search for: http://yourdomain.com and Replace with: https://yourdomain.com
    • Select all tables EXCEPT wp_options
  1. Debugging with Browser Tools

However, if you have the developer access, then you can navigate to your Chrome DevTools>> Console tab, look for “Mixed Content” warnings, and resolve the root causes accordingly.

2. SSL Not Working After Installation

Have you installed an SSL certificate on WordPress, but realize that it is not working?

We’ve got you. Here’s what to do next:

  1. Clear Browser Cache
    • Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac)

  1. SSL/TLS Settings: Enable “Always Use HTTPS”
  2. DNS Configuration
    • Ensure the orange cloud icon is enabled
    • Verify nameservers point to Cloudflare
    • Check for outdated DNS records
  1. Edge Certificates
    • Confirm the certificate is active
    • Check for any security warnings

By using these troubleshooting steps properly, you can resolve the most common SSL WordPress certificate issues and ensure your website maintains secure HTTPS connections. Also, remember to always back up your site before making significant changes.

How to Keep Your SSL Certificate Active & Secure

After you have successfully installed your SSL WordPress certificate, you must ensure it is active and working as intended. To ensure the WordPress SSL certificate is working efficiently and actively:

1. Enable Auto-Renewal (Critical for Free SSL Certificates)

Free SSL certificates (like Let’s Encrypt) expire every 90 days. Auto-renewal prevents unexpected website downtime due to WordPress SSL expiration.

How to Set Up

Here are some simple ways to set up auto-renewal options on your SSL WordPress certificate:

Pro Tip: Some hosts disable auto-renewal by default. But you should always verify in your control panel.

2. Monitor Certificate Expiry

An expired SSL breaks HTTPS security, which can hurt SEO and user trust.

Best Monitoring Practices

The best monitoring practices to help you stay aware of your SSL certificate breakage are:

openssl x509 -enddate -noout -in /etc/ssl/your_certificate.crt

3. Regularly Check for Security Vulnerabilities

Outdated SSL protocols can easily expose sites to cyber attacks. Hence, it is necessary to ensure a monthly checkup on your WordPress SSL certificate. Here we have designed a checklist for you to keep and edit to help maintain the monitoring process:

Monthly Security Checklist (Advanced Level):

  1. Test SSL configuration at SSL Labs.
  2. Disable weak protocols (TLS 1.0/1.1) in hosting settings
  3. Update cipher suites to prioritize, such as AES-256 encryption or ECDHE key exchange.    
  4. Add security headers in .htaccess:

Header set Strict-Transport-Security “max-age=31536000; includeSubDomains; preload”

WordPress SSL Certificate FAQs

Why is my SSL certificate not working after installation?

If your SSL isn’t working post-installation, follow this troubleshooting checklist:
Clear browser cache (Ctrl+Shift+Delete) and test in incognito mode
Verify certificate installation using SSL Shopper’s SSL Checker
Check server configuration to ensure HTTPS is enforced. 
Confirm your hosting provider installed the certificate correctly

How do I fix mixed content warnings after enabling SSL?

Mixed content occurs when your HTTPS site loads HTTP resources (images, scripts). Fix it by:
Plugin Method: Install Really Simple SSL (auto-fixes 95% of mixed content)
Manual Method:
Update hardcoded HTTP links in: Theme files like header.php and footer.php
Database content (use Better Search Replace plugin)
Add this to the wp-config file:
define(‘FORCE_SSL_ADMIN’, true);

How long does it take for an SSL certificate to activate?

Most SSL certificates activate instantly or within minutes after installation. However:
Free SSLs (Let’s Encrypt): Immediate activation
Paid SSLs: May take 1-24 hours for full activation
Browser caching: Some visitors might still see “Not Secure” for up to 48 hours
Quick check: Use SSL Labs’ SSL Test to verify activation status.

Why does my WordPress site show “Not Secure” even with SSL?

This usually happens when:
Some pages still load over HTTP
Fix: Update all internal links to HTTPS (use the “Better Search Replace” plugin)
Your SSL certificate expired
Fix: Renew it (most hosts auto-renew Let’s Encrypt certificates)
Browser is loading cached HTTP version
Fix: Clear cache or test in a new incognito window

Keeping your SSL certificate secure requires just three key habits, which include regular maintenance to ensure that the SSL has not expired, and proper monitoring to ensure the SSL is functioning correctly.
