I've setup the multisite on a fresh installation of WordPress.

Then I created some other websites, so, in the end, I have something like this

I have then installed an SSL digital certificate, so I changed the URLs of the websites to match the HTTPS scheme:

To change the scheme I gone to Sites > All Sites, then clicked on each site and in tab "Information" (the first one) I simply changed the scheme and saved.

This worked.

The only site left without the https is http://example.com: for this, in fact, I have cannot change the URL.

If I go to Sites > All Sites and click on it, in fact, in the first tab "Information" the URL is not editable and is in the form http://example.com, without the https scheme.

How can I change it?

I'd like to change it now, before I start to install plugins and write articles.

Any suggestions?

I would suggest editing the wp-config.php file, and adding:


However for multisite here it says you should edit DOMAIN_CURRENT_SITE and PATH_CURRENT_SITE, if there is such thing defined in a multisite wp-config.

First suggestion is based on this article.


I would just:

  1. Comment out the multisite code in wp-config.php
  2. Login again to WP
  3. Go back to settings and reading as if a single site.
  4. change http to https
  5. uncomment multisite code in wp-config.php
  6. Proceed as normal

It seems some updates to WP core have improved things. I had a warning in Site Health, saying that the site wasn't configured to use HTTPS. 'Click here to fix it' it said. So I did, and now the site uses https. Your mileage may vary but it's by far the easiest thing to try first.


It worked for me!

In fact, I just had to temporarily change:

define('MULTISITE', true);


define('MULTISITE', false);
  • Is that Jesus's answer or D.Dan's answer that you're agreeing with? (I think Jesus was effectively suggesting the same thing by commenting out the MULTISITE define.)
