SSL 404 Error with WordPress Multisite

Did you change WP for that site to be SSL?

I do it this way: https://halfelf.org/2014/ssl-for-one-domain-on-multisite/

The SSL cert is issued for the subdomain my multisite is installed on. I added the snippet of code that forces WordPress to use SSL on the login page and dashboard, which works fine.

Here’s what in my .htaccess file.

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress

# BEGIN wtwp_cache
# END wtwp_cache

# BEGIN wtwp_security
# END wtwp_security

And did you remember to edit the home/site URLs? You probably have to do it in the database, since I’m pretty sure you can’t edit http/https on network admin anymore.

I would probably just do a serialization safe search for https://subdomain and change it to https.

Well…I tried changing the page url from “https://&#8221; to “https://&#8221; my phpMyAdmin. But it still produced a 404 error. O, and I made a mistake from my earlier post. My subsite’s login and admin dashboard over SSL produces a 404 error too : (

https://MappedDomain.domain.com/page <- Doesn’t Work

What’s the 404 look like?

I finally fixed it after, what felt like a lifetime of editing virtual host files.

DocumentRoot /Directory/of/Website/

    <Directory />
        Options FollowSymLinks
        AllowOverride All
    </Directory>
    <Directory /Directory/of/Website/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>

Change “none” in the “AllowOverride” lines to “all” in the Virtual Host config for port 443. Or whatever port you have SSL running on.

Thanks for the help Mika : )
