Spoke to Support and now have new issues SSL/HTTPS

Hello thanks for your help earlier today. I made the https:// changes that we discussed a few in wp_options and wp_sitemeta

Now my primary domain is working properly and uses https:// but a new issue has started. When a user tries to create their site, it forces them to "view it" with a link to https:// YOUR NEW SITE

This immediately causes "certificate" issues and browser warnings

How do I change the part of wp-signup.php to reflect a link that shows HTTP:// YOUR NEW SITE
