Ensures logins are always done via SSL on a subdomain of the master domain, but access to custom domains are always over HTTP, to avoid cert errors.
Ensures logins are always done via SSL on a subdomain of the master domain, but that access to custom domains are always done over HTTP, to avoid certificate errors. For WordPress Multisite.
FORCE_SSL_ADMIN directives in
wp-config.php work great, but are too restrictive in situations where you have custom domains — custom domains for which you cannot have SSL certificates. For sites on custom domains, we need to make sure that the login and admin access happens over the subdomain, which can be properly served over HTTPS.
or, a readme you should read before implementing this plugin on your site.
This plugin filters the login, logout, home and admin URLs that WordPress uses to generate its internal links.
Why do we do this?
We have a WordPress Multisite network. Let's call it
mynetwork.com. We bought a fancy SSL wildcard certificate so we can offer
*.mynetwork.com over a secure connection.
We’d very much like to use this secure connection for all logins, and for all admin access.
We also allow sites on this network to use a custom domain — like
demo-site.com. We might be using WPMU Domain Mapping to achieve this. These sites have two domains, then —
If we switch on
FORCE_SSL_ADMIN, we have a problem. When users go to
https://demo-site.com/wp-login.php, they get a certificate error. We have a wildcard certificate for
*.mynetwork.com, but we can’t possibly have a valid SSL certificate installed for every custom domain!
Instead, we want to force all login pages and admin pages to be:
We want all regular access to be:
This plugin facilitates that — rewriting the
wp-login (including logout) and
wp-admin URLs to the first example, and rewriting all the others to the second style.
This plugin makes some (foolish) assumptions about your multisite network. You must make sure that these assumptions are true for your site, or you will find that this plugin may have unintended consequences and break things that are difficult to fix without manually disabling the plugin.
Your subdomains are in the format:
ais, for example:
bis, for example:
amust be a single domain component. (
acan't be, for example:
Your wildcard certificate is configured properly for:
So if your network site URL is
http://www.mynetwork.com, your wildcard cert will be fine. If it is just
mynetwork.com, you will need another cert to avoid errors when you go to
Your site already has the custom domains working.
You have the
FORCE_SSL_LOGIN setting in
You have the
FORCE_SSL_ADMIN setting in
wp-config.php false. We’ll handle that — WordPress’ forcing of SSL admins will conflict with this plugin.
