Forcing (Subdomain) Multisite to Create New Subsites with HTTPS
As a web developer or site owner, ensuring the security and privacy of your website and its users is of utmost importance. One crucial aspect of this is implementing HTTPS (Hypertext Transfer Protocol Secure) across your entire website, including any subdomains or subsites. This article will explore the steps you can take to force your WordPress (subdomain) multisite to create new subsites with HTTPS, providing you with a seamless and secure web experience for your users.
The Importance of HTTPS in Multisite Environments
HTTPS is a widely adopted security protocol that encrypts the communication between a user's web browser and the web server, preventing unauthorized access and protecting sensitive information, such as login credentials, payment details, and personal data. In a WordPress multisite environment, where you may have multiple subsites or subdomains, it's crucial to ensure that all of these components are secured with HTTPS.
There are several reasons why you should enforce HTTPS for your WordPress multisite:
-
User Security: HTTPS helps protect your users' data and privacy by encrypting the connection between the user's browser and your website. This is especially important if your subsites handle any sensitive information, such as login credentials or e-commerce transactions.
-
SEO and Google Ranking: Google and other search engines favor websites that use HTTPS, and they may penalize sites that don't. Implementing HTTPS can improve your website's search engine rankings and visibility.
-
Browser Compatibility: Modern web browsers often display security warnings or block content on non-HTTPS sites, which can negatively impact the user experience and potentially deter visitors from accessing your website.
-
PCI Compliance: If your WordPress multisite includes any e-commerce functionality, such as an online store, HTTPS is a requirement for PCI (Payment Card Industry) compliance, which is necessary to securely process credit card transactions.
Methods to Force HTTPS for New Subsites in WordPress Multisite
There are a few different approaches you can take to ensure that new subsites in your WordPress multisite environment are automatically created with HTTPS. Let's explore each method:
1. Modify the .htaccess File
One of the simplest ways to force HTTPS for new subsites is to add the following code to your WordPress multisite's .htaccess
file:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This code will automatically redirect any HTTP requests to their HTTPS counterparts, ensuring that all new subsites are accessed over a secure connection.
To implement this solution:
- Locate your WordPress multisite's
.htaccess
file, which is typically found in the root directory of your WordPress installation.
- Open the
.htaccess
file in a text editor and add the code snippet above.
- Save the file and upload it back to your server.
From this point forward, any new subsites that are created in your WordPress multisite environment will be automatically redirected to HTTPS.
2. Use a "Force SSL" Plugin
Another option is to use a WordPress plugin that specializes in forcing HTTPS across your entire multisite network. One popular plugin for this purpose is Really Simple SSL. This plugin automatically detects your SSL/HTTPS configuration and applies the necessary settings to ensure that your website is fully secured.
To use the Really Simple SSL plugin:
- Install and activate the plugin across your entire WordPress multisite network.
- Navigate to the plugin's settings page and configure the desired HTTPS settings.
- The plugin will then automatically handle the process of redirecting HTTP traffic to HTTPS for all new subsites.
The advantage of using a plugin like Really Simple SSL is that it provides a user-friendly interface for managing your HTTPS configuration, which can be particularly useful if you're not comfortable directly editing your .htaccess
file.
3. Specify HTTPS in Domain Mapping Plugins
If you're using a plugin that handles domain mapping for your WordPress multisite, such as WordPress Multisite Domain Mapping, you can also specify HTTPS in the plugin's settings.
To do this:
- Install and activate the domain mapping plugin across your WordPress multisite network.
- Navigate to the plugin's settings page and locate the option to specify the protocol (HTTP or HTTPS) for your mapped domains.
- Select "HTTPS" as the protocol and save the settings.
This approach ensures that any new subsites that are mapped to custom domains will automatically use the HTTPS protocol, providing a consistent and secure user experience across your entire multisite network.

Verifying and Testing HTTPS Implementation
After implementing one of the above methods, it's essential to verify that the HTTPS configuration is working as expected. Here are a few steps you can take to test your HTTPS implementation:
- Check the Site's URL: Visit a few of your subsites and ensure that the URL starts with
https://
instead of http://
.
- Inspect the Site's SSL/TLS Certificate: Use a tool like the SSL Labs Server Test to check the validity and configuration of your SSL/TLS certificate.
- Test for Mixed Content Issues: Navigate to your subsites and check the browser's developer tools for any mixed content warnings, which can occur if your site is still loading some resources over HTTP.
- Utilize Google's Search Console: If you've set up Google Search Console for your WordPress multisite, you can use it to monitor your site's HTTPS implementation and identify any security or indexing issues.
By thoroughly testing and verifying your HTTPS implementation, you can ensure that your WordPress multisite is providing a secure and seamless experience for your users.
Conclusion
Enforcing HTTPS for new subsites in a WordPress multisite environment is a crucial step in securing your website and protecting your users' data. By using one of the methods outlined in this article – modifying the .htaccess
file, employing a "Force SSL" plugin, or specifying HTTPS in a domain mapping plugin – you can ensure that all new subsites are automatically created with HTTPS, providing a consistent and secure user experience across your entire network.
Remember to thoroughly test your HTTPS implementation to identify and address any potential issues, such as mixed content warnings or certificate validation problems. By taking these steps, you'll not only improve the security of your WordPress multisite but also enhance its search engine optimization and compliance with industry standards.
