Really Simple SSL

Installing an SSL certificate

Really Simple SSL requires a valid SSL certificate to migrate your website to https. If your website does not have an SSL certificate, you will be shown the following warning message:

If you see this notice, please click on the ‘Reload over https’ button. If this doesn’t work, your site likely uses an invalid SSL certificate. You can test your certificate by entering your domain here: If you don’t get at least a B rating when you scan your site, you probably don’t have a valid SSL certificate yet. A valid SSL certificate is required for Really Simple SSL to work.

If you would like to get a free SSL certificate, you are in luck, thanks to Let’s Encrypt – An open certificate authority (CA), run for the public’s benefit. While Let’s Encrypt does not have a WordPress plugin, you can use the SSL Zen or WP Encryption plugin which help you to generate and install a free SSL certificate from Let’s Encrypt.

You can easily add a free SSL certificate with WP Encryption or SSL Zen plugin. These plugins allows you to generate a free Let’s Encrypt certificate. A Let’s Encrypt certificate is a free SSL certificate.

How to install a free SSL certificate using SSL Zen

SSL Zen has two plans – Free and Premium. Here’s a quick comparison between the plans:

Using SSL Zen – Step 1

Once installed, navigate to the SSL Zen wizard:

If your website uses the www sub-domain, click on ‘Include www-prefixed version too?’ Make sure the email address entered is valid as all the SSL certificate renewal notices will be sent to this email. Click on ‘I agree to Terms and Conditions’ and then on the Next button.

Using SSL Zen – Step 2

SSL Zen requires you to prove your domain ownership by either uploading an HTML file on your website or adding a TXT record from your domain panel. We recommend using DNS verification as the process is fairly easy compared to HTTP verification.

If the DNS verification fails for some reason, only then try the HTTP verification method.

How to install a free SSL certificate on your cPanel hosting environment using WP Encryption

Install WP Encryption by navigating to the Plugins section in your WordPress Dashboard, pressing ‘Add new’, and entering ‘WP Encryption’ in the plugin search box. WP Encryption should now appear. Install it by clicking the ‘Install’ button.

After installing, a dialog notifying you about opting in for updates appears. You can either opt-in or skip this message. Afterward, you can choose one of two plans: the basic and pro plans. The basic plan is free while the pro plan can be bought for $49/lifetime.

Once you have passed the opt-in and plan screens, the SSL certificate can be requested.

Using WP Encryption – Step 1

The first step requires you to enter your e-mail address and agree to the plugin terms. The first checkbox asks whether you want to generate the SSL certificate for both the www and non-www domains. We recommend enabling this option. Having both the www and non-www domains on the certificate is considered a best practice.

    1. Hi Malik,

      Do you mean that the SSL Zen plugin is not free? We don’t have any ties with SSL zen, but as far as I can tell it’s still free. If this is not what you mean, can you be a bit more specific?
