How to Add Free SSL in WordPress with Let’s Encrypt

In today's digital landscape, security is paramount, especially if you're running a website. With rampant cyber threats and the importance of maintaining user trust, implementing HTTPS via an SSL (Secure Sockets Layer) certificate is no longer optional—it's essential. Fortunately, there's a fantastic solution that allows you to secure your WordPress site for free: Let's Encrypt. This efficient certificate authority provides free SSL/TLS certificates, making it easier for entrepreneurs and bloggers alike to secure their sites without breaking the bank.

In this article, we’ll walk you through the step-by-step process of adding a free SSL certificate to your WordPress site with Let's Encrypt. By the end of this guide, you’ll not only know how to implement SSL but also understand why it's crucial for your online presence.

What is Let's Encrypt?

Let's Encrypt is a free, automated, and open Certificate Authority (CA) that provides SSL/TLS certificates for websites. It is a widely trusted resource that allows you to implement encrypted connections on your site without any cost. Here’s why Let’s Encrypt has gained immense popularity:

• Cost-effective: Completely free to use, making it accessible for everyone.
• Automated process: Many hosting providers offer one-click installations.
• Trustworthy: Backed by leading organizations like Mozilla, Chrome, and the Internet Security Research Group (ISRG).

Implementing Let's Encrypt will not only secure your communications but also boost your SEO, as Google considers HTTPS as a ranking factor. Let’s dive into the steps for adding free SSL using Let's Encrypt.

Step 1: Check Your Hosting Environment

Before proceeding, it's crucial to ensure that your hosting provider supports Let's Encrypt. Most reputable hosting services nowadays do. Here’s how to check:

• Log into your hosting control panel (e.g., cPanel, Plesk).
• Look for the SSL/TLS section.
• Check if you see an option for Let's Encrypt or “Free SSL”.

For example, if you’re using hosts like Bluehost, SiteGround, or DreamHost, they typically offer easy integration with Let’s Encrypt. If your host does not support it, consider switching to a host that does, for better security and flexibility.

Example Hosting Providers Supporting Let's Encrypt

• Bluehost
• SiteGround
• A2 Hosting
• DigitalOcean (with additional configuration)

Step 2: Installing the SSL Certificate

The installation process may vary slightly depending on your hosting provider. However, the general steps are straightforward. Here’s a simplified approach to get your SSL certificate installed:

1. Go to your hosting dashboard.
2. Navigate to the SSL/TLS or Security section.
3. Select the option for Let's Encrypt, then choose the domain you wish to secure.
4. Click on Install.

For instance, when using cPanel:

• Locate the “Let's Encrypt” icon in the Security tab.
• Choose the domain from the dropdown.
• Click “Issue” to begin the installation.

Automating SSL Renewal

Let’s Encrypt certificates are valid for 90 days, but they can be renewed automatically through your hosting service. Ensure that auto-renewal is enabled to avoid any unexpected downtime.

Step 3: Configuring HTTPS on Your Website

Once your SSL certificate is installed, you’ll want your entire site to use HTTPS, not just the homepage. Here's how to do it:

• Log into your WordPress admin dashboard.
• Go to Settings > General.
• Change your WordPress Address (URL) and Site Address (URL) from HTTP to HTTPS.
• Save changes.

Now, to avoid mixed content issues (where your site tries to load both HTTP and HTTPS content), it's essential to update any existing links to their HTTPS versions. You can use a plugin like Really Simple SSL to help with this process.

Using a Plugin for HTTPS Fixes

• Really Simple SSL: Automatically detects your settings and configures your website to run over HTTPS.
• Better Search Replace: Use this to search your database for HTTP links and replace them with HTTPS.

Step 4: Testing Your SSL Installation

After completing the installation and configuration, it’s crucial to ensure your SSL certificate is working properly. Use the following methods for testing:

• Visit your website using https:// and check for the padlock symbol in the address bar.
• Use an SSL checker tool (like SSL Shopper) to verify your certificate's installation.

A successful installation will indicate that your website is secure. Conversely, if there's an error, you may need to revisit your host's settings or configurations.

Potential Issues to Trouble-Shoot

• Mixed Content Errors: Ensure all resources (images, CSS, JS) are loaded over HTTPS.
• Browser Caching: Clear your browser cache and reload to see changes.

Securing your WordPress website with a free SSL certificate from Let's Encrypt is a straightforward process, yet it is a critical step toward ensuring data privacy and security for both the site owner and the users. We’ve covered how to check for hosting support, install the SSL certificate, configure HTTPS, and troubleshoot potential issues.
