In this step-by-step guide, you’ll learn how to set up free SSL for WordPress, verify your domain, generate a Let’s Encrypt certificate, install it on your web server, and enable HTTPS across your website.

WP Encryption is designed to simplify the SSL process by handling the Let’s Encrypt certificate generation and domain verification from inside the WordPress dashboard. The plugin is available through the official WordPress Plugin Directory.

What Is a Free SSL Certificate?

An SSL certificate encrypts the connection between your website and your visitors’ browsers. Once SSL is installed, your website can be accessed using https:// instead of http://.

Let’s Encrypt provides free Domain Validation (DV) SSL certificates. WP Encryption makes the process easier by providing a WordPress-based interface for requesting and generating the certificate.

After SSL is correctly installed, visitors should see the secure HTTPS connection and browser security indicator when visiting your website.

Why Use Let’s Encrypt SSL for WordPress?

Let’s Encrypt is a popular choice for websites that need a free SSL certificate. You don’t need to purchase a traditional SSL certificate simply to enable HTTPS on a standard WordPress website.

• Free SSL certificate: No certificate purchase is required.
• HTTPS encryption: Encrypts traffic between your website and visitors.
• Domain validation: The certificate verifies control of the domain.
• Works with WordPress: You can generate the certificate from the WordPress dashboard using WP Encryption.
• Easy certificate generation: WP Encryption guides you through domain verification and certificate generation.

What You Need Before Installing Free SSL

Before generating your certificate, make sure:

• You have administrator access to your WordPress dashboard.
• Your domain is already pointing to your web server.
• Your WordPress website is accessible over the internet.
• You have access to your web hosting control panel.
• You can install an SSL certificate on your hosting account.

If your domain is not correctly pointing to the server, Let’s Encrypt may not be able to verify domain ownership.

How to Add Free SSL Certificate to WordPress

Step 1: Install WP Encryption

First, install the WP Encryption plugin on your WordPress website.

1. Log in to your WordPress admin dashboard.
2. Go to Plugins → Add New.
3. Search for WP Encryption.
4. Click Install Now.
5. Click Activate.

WordPress supports installing plugins directly from the Plugin Directory through Plugins → Add New.

After activation, you should see the WP Encryption option in your WordPress admin menu.

Step 2: Open the SSL Installation Page

From your WordPress dashboard, open:

WP Encryption → SSL Install

The plugin provides a step-by-step SSL generation process. You will be asked to provide the information required to generate your free Let’s Encrypt certificate.

Step 3: Start the Free SSL Certificate Generation

Start the SSL generation process and enter the email address requested by the plugin.

Make sure you use an email address that you can access. The email address is associated with the Let’s Encrypt certificate registration process and important certificate-related communications.

Before continuing, review and accept the applicable Let’s Encrypt terms and the WP Encryption terms presented in the SSL generation interface.

Step 4: Verify Your Domain

Let’s Encrypt requires proof that you control the domain before issuing an SSL certificate.

WP Encryption guides you through the domain verification process. Depending on your website configuration, you may be presented with verification instructions that require you to place verification information on your website or configure DNS.

Follow the verification instructions displayed by WP Encryption and complete the required verification.

Important: Make sure your domain resolves correctly to the server where the WordPress website is hosted. If the domain points somewhere else, domain validation can fail.

Step 5: Generate Your Let’s Encrypt SSL Certificate

Once domain ownership has been successfully verified, continue with the SSL generation process.

WP Encryption communicates with the certificate authority and generates your SSL certificate. The plugin is specifically designed to simplify this process so that you don’t have to manually create a CSR and perform the traditional certificate-request workflow.

When successful, WP Encryption will display a certificate generation success message and provide the generated SSL certificate information.

Step 6: Download Your SSL Certificate and Private Key

In the free version of WP Encryption, the generated certificate can be downloaded and manually installed on your web server.

Download the certificate and private key files provided by WP Encryption and keep them secure.

Step 7: Install the SSL Certificate on Your Hosting Server

Generating an SSL certificate and installing it are two separate steps.

The certificate needs to be installed on the web server that handles HTTPS traffic for your domain. The exact procedure depends on your hosting provider and server control panel.

If your hosting provider uses cPanel, look for the SSL/TLS management section and use the option for installing or managing SSL certificates for your domain.

If you’re not sure how to install the certificate, contact your hosting provider and provide the generated certificate files. Your host can install the certificate on the appropriate virtual host or domain.

Step 8: Check Your Website Over HTTPS

After your hosting provider has installed the certificate, open your website using:

https://example.com

Replace example.com with your actual domain.

Your browser should now establish a secure HTTPS connection with the website.

You can also use WP Encryption’s SSL health and security features to check the status of your SSL configuration.

Step 9: Force WordPress to Use HTTPS

Installing the certificate does not necessarily mean that every HTTP request will automatically redirect to HTTPS. You should configure your website to use HTTPS consistently.

WP Encryption includes a Force HTTPS feature that can redirect visitors from HTTP to HTTPS after a valid SSL certificate has been installed.

Open the relevant HTTPS/Force HTTPS section in WP Encryption and enable the appropriate HTTPS redirect method.

WP Encryption recommends the htaccess method for server-level redirection in typical configurations and recommends the WordPress method when using services such as Cloudflare or other reverse proxies.

How to Fix WordPress Mixed Content After Installing SSL

One of the most common problems after switching to HTTPS is mixed content.

Mixed content occurs when your main website loads over HTTPS but some resources, such as images, JavaScript, CSS files, fonts, or external resources, are still requested using HTTP.

For example:

https://example.com
http://example.com/wp-content/uploads/image.jpg

The second URL is still using HTTP and can cause browser security warnings or prevent the secure padlock from appearing correctly.

WP Encryption includes tools for identifying insecure and mixed-content resources and also provides HTTPS enforcement functionality.

Fix WordPress URLs

Make sure your WordPress Address (URL) and Site Address (URL) use HTTPS.

Go to:

Settings → General

Check that your website URLs begin with:

https://

Do not change these URLs before the SSL certificate is actually working, because doing so prematurely can make your WordPress dashboard inaccessible.

How to Check Whether Your Free SSL Is Working

After installing your Let’s Encrypt certificate, perform these checks:

1. Open your website using https://.
2. Check that your browser does not display a certificate warning.
3. Open several pages of your website.
4. Test your WordPress login page.
5. Check images, CSS and JavaScript files.
6. Verify that HTTP requests redirect to HTTPS if Force HTTPS is enabled.
7. Run an SSL health/security check.

WP Encryption provides SSL health and security-related checks from within WordPress.

Does Let’s Encrypt SSL Cost Anything?

No. Let’s Encrypt provides free Domain Validation SSL certificates.

Using WP Encryption, you can generate the certificate from your WordPress dashboard without purchasing a traditional SSL certificate.

How Long Does a Let’s Encrypt SSL Certificate Last?

Let’s Encrypt certificates have a limited validity period and need to be renewed regularly. Therefore, SSL renewal is an important part of maintaining HTTPS on your WordPress website.

WP Encryption provides an SSL renewal workflow. Its documentation states that the renewal option becomes available during the final 30 days before certificate expiration, allowing you to repeat the certificate-generation process.

The WP Encryption Pro version provides automatic certificate renewal functionality, while the free workflow requires manual involvement.

Can I Use Free SSL for a Business WordPress Website?

Yes. A Let’s Encrypt Domain Validation certificate can provide HTTPS encryption for business websites, blogs, WooCommerce sites, portfolios, and many other types of websites.

Keep in mind that a DV SSL certificate validates control of the domain. It does not serve as a comprehensive verification of the identity or legitimacy of the business operating the website.

Free SSL WordPress: Common Problems and Solutions

Domain verification fails

Check that your domain’s DNS records point to the correct server and that the website is publicly accessible. Also check whether a CDN, proxy, firewall, or security rule is interfering with the validation request.

SSL is installed but the website still shows HTTP

Installing the certificate does not automatically guarantee that every HTTP URL will redirect to HTTPS. Enable the appropriate Force HTTPS option after confirming that the certificate works correctly.

The padlock is missing

This can be caused by mixed content. Check whether images, scripts, stylesheets, fonts, or other resources are still being loaded over HTTP.

My website stopped working after enabling HTTPS

If HTTPS enforcement was enabled before the certificate was correctly installed, temporarily disable the HTTPS enforcement mechanism and verify the certificate installation first.

www and non-www are behaving differently

If you want your SSL certificate to cover both www.example.com and example.com, make sure both versions are accessible and correctly configured for domain verification. WP Encryption provides an option for generating SSL for both www and non-www when the domain configuration permits it.

Free SSL vs Paid SSL for WordPress

For most standard WordPress websites, the primary goal of SSL is to establish an encrypted HTTPS connection. A free Let’s Encrypt certificate can accomplish this without the cost of purchasing a traditional SSL certificate.

Why Use WP Encryption to Generate Free SSL?

Generating an SSL certificate manually can be intimidating if you’re not familiar with certificate requests, domain validation, private keys and server configuration.

WP Encryption brings the certificate-generation workflow into the WordPress dashboard and provides additional HTTPS and SSL security tools.

In addition to SSL generation, WP Encryption includes features for HTTPS redirection, SSL health checks, security headers and mixed-content detection.

Why Use X-Frame-Options?

Clickjacking is a type of cyber attack where malicious sites embed your page in a transparent iframe to trick users into interacting with invisible elements—potentially revealing sensitive data or triggering unintended actions. Setting the correct X-Frame-Options header ensures your content can’t be embedded by untrusted domains.

How Does X-Frame-Options Work?

Better Alternative: Content Security Policy (CSP)

While X-Frame-Options offers solid baseline protection, CSP with frame-ancestors is the modern recommendation for finer control:

Content-Security-Policy: frame-ancestors ‘self’

This achieves the same anti-clickjacking effect and more across modern browsers.

Key Takeaways

• Set X-Frame-Options to “SAMEORIGIN” or “DENY” for clickjacking protection
• If you want your site to be loaded in an iFrame on a different domain, don’t set the X-Frame-Options header.
• Consider using CSP frame-ancestors for broader compatibility and advanced control
• Combine with other headers (like X-XSS-Protection, Content-Security-Policy, and Strict-Transport-Security) for a more secure web application
