This is why if your site doesn’t have a WordPress multisite install option or certificate, there will be a proper warning at the top right corner of your page—suggesting that the site might be susceptible to hackers and to activate SSL in WordPress immediately. Besides, the users entering your site will consider it shady in general, lowering your overall authority.

On the other hand, if you don’t install an SSL certificate WordPress, you might not receive your customers’ payments if you run an e-commerce site. Thus, your business might not be able to generate sales that you richly deserve.

But do not worry, as we will guide you through how to add HTTPS to the WordPress site and to set up SSL certificate WordPress in just a couple of minutes. And it doesn’t matter if you’re a techy person or not; either way, we got you covered!



This leads us into the next piece which is HTTPS.  So, what is HTTPS and why should you care?  HTTPS stands for Hypertext Transfer Protocol. It is common to encrypt the data and information through end-to-end routes that you send and receive from different sites. You can be protected from losing your personal data to the middleman or ISP’s in the connection through this.

In short, through harmful means, someone can hack the biased connection between you and the server and take in all the vital information like credit card numbers without even realizing it. However, with the aid of HTTPS, your data over the Internet is secured and adequately encrypted, and even your domain name is not shared with unknown sources. 

So, it takes the encrypted data created by SSL/TLS and puts it on a bus.  Then drives that bus of encrypted data back and forth between your WordPress site and the users’ browser.  If the WordPress multisite SSL data is intercepted it cannot be read by anyone and therefore remains private. This is the safest way to create a WordPress multisite SLL with the least amount of drawbacks.


As we discussed before, encryption is a vital component that one should consider for proper security on the Internet. The HTTPS in your website or browser represent appropriate encryption as you connect with your server.

The third-party sources can see the connection but won’t read to decode the information passing through. In real life, let’s say that the package you will be sending to someone has been locked in a box with a specific key provided by the person/server.

As you send that package in the closed container, no one can open it, even if they receive one. But the person that already has the key will be able to open it with ease. This is the way through how to make website secure WordPress as HTTPS works within cyberspace. And this is the reason why you should set up SSL (HTTPS) on WordPress multisite

How to secure the communication on my WordPress Multisite instance?

First to secure WordPress multisite SSL, you need an SSL Certificate.  You can purchase an SSL certificate or on most hosting plans you can use Let’s Encrypt to generate a free one. An SSL Certificate is like a key you would use for your house.  Just like the key for your front door, you use a certificate to lock the door and protect the data.  The only one with a “key” can access the content you create. 

 A certificate is the key but instead of locking your front door it is locking/encrypting the data on your website to be sent to someone who wants to access it. What you don’t see under the hood is that any user who wants to access your website securely gets a key. 

This authenticates your site and proves they are communicating with the intended website, it authorizes them and allows them to access the content. It also provides encryption of the data as well as the integrity of the data. 

In other words, the data cannot be viewed by someone who is unauthorized and the data cannot be modified without being detected. This type of key is a public key, which means that anyone who is authorized can access the content.  The content is delivered in a secure manner so no-one can alter it, everyone gets authorized to view the content.

Methods of Setting up SSL Certificate WordPress


Before you Set Up SSL (HTTPS) on WordPress multisite, you first need to activate SSL in WordPress (certificate). You can do this by contacting your web hosting provider and requesting them directly. Most of them will avail you of this certificate free of cost, while others like COMODO PositiveSSL will charge you anywhere around $9 per year.

Most of them provide free WordPress multisite install option or certificate, even in their cheapest package due to competitions. Now, this is one side of the story. The other procedure includes some changes to WordPress multisite setup so your site can easily be on the secured version of Google. And you can do it within no time.

After going through, how to enable SSL certificate in WordPress, the next question you guys might be naturally asking might be how to add HTTPS to WordPress site. If that’s the case, just like previous procedures, this process is super straightforward, based upon the following steps.

    1. Disable any caching and minifying plugins as you select the WordPress multisite install option.
    2. Ensure all your external assets are loaded over HTTPS (scripts, CSS files, images, etc.)
    3. Create an SSL-certificate (most hosting companies allow you to do this with the click of a mouse – thanks to or you can contact WordPress how to support SSL)
    4. Change all hardcoded URLs of your site that begin with HTTP to HTTPS. You’ll need to dive into the database to do this. I use this search and replace script, but you can also use Adminer or PhpMyAdmin. WPEngine has a list of where to look. Don’t forget to delete the script from your server when you’re done!
    5. If your site doesn’t redirect automatically from HTTP to HTTPS, add Apache redirects.
    6. Make sure everything works as expected after you enable SSL WordPress.
    7. Change the URL in external services like analytics and monitoring sites.

WordPress Multisite:

A WordPress Multisite SSL can mean different things but in this article it means:

  • A multisite setup as subdirectories
  • A multisite setup as sub-domains
  • A multisite setup as multiple domains

Let’s go over each one briefly, so you can understand the multisite WordPress setup and the reason behind applying SSL to my WordPress site.

Multisite | Subdirectories

Think of a subdirectory as a folder within a filing cabinet.  The filing cabinet is your website and the folder is a different page, post, or category on your website Here are some examples:


Once you install SSL WordPress multisite setup on the URL [] all the other subdirectories “about us”, “contact us”, “home” will inherit the SSL.  There is no need to configure them individually.

Multisite | Sub-Domains

Sub-domains are just that, a sub-section or tertiary domain name you can use to point to different sections of your website’s content. Here are some examples:


If your site consists of multiple sub-domains, you should use a wildcard ssl certificate.  This means that when you create the certificate you would use the “*”. The asterisk in front of the main domain is critical because any sub-domain you setup will inherit the SSL certificate and provide the needed security.

Multisite | Multiple Domains

If you have different domains on a single hosting account or setup under a multisite tenant, you will need a certificate for each one.  However, there are options available to create what is called a multi-domain SSL certificate which will cover all domains hosted on a single server. Here are some examples:


As you can see each site is independent in its own way.  However, using a multi-domain SSL certificate is one option to streamline your security and provide a high level of trust for your website patrons. If you’re still puzzled, try contacting the wordpress how to support ssl.
