How to secure wp-signup.php with SSL?

Am hoping the question is self explanatory. I have SSL setup and working perfectly via the Wordpress HTTPS plugin, but I can't find a way to designate a core WP file (non-login) as one to be encrypted. Can anyone help? TIA.

Thanks much for the fast reply, Vinod. I added the 'define' statement to my config file, but there is no change.

/wp-signup.php still loads unencrypted unless the url starts with https://.

Almost want to let you off the hook with this problem, Vinod. You've designed a beautiful solution on another thread that lets me bypass /wp-signup.php for the first blog created by a user. I'll only use this page now when a user creates an additional blog, which is a rare occurrence. Please do resolve this if you can, as others may need a solution as well, but the pressure is off. Thanks much for your efforts.

Hello @Burlington Avenue

I hope you are well today. Would you please try the following in your htaccess:
```
RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} ^/wp-signup.php?
RewriteRule ^(.*)$ https://www.DOMAIN.com/$1 [R,L]
```
Don't forget to change your domain name :slight_smile:

Hope it helps :slight_smile: Please feel free to ask more question if you have any.

Cheers
Ash

Thanks, Ash. My .htaccess file contains a statement affecting /wp-signup.php, for redirecting to a custom file, so I'm leery of adding these new statements without checking. Under some caching statements, my file states:

# BEGIN WordPress
RedirectMatch 301 ^/blog/([0-9]{4})/([0-9]{2})/([0-9]{2})/([^/]+)/$ http://example.com/$4
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
# redirect to custom signup form
RewriteRule ^wp-signup.php(.*)$ wp-content/themes/[my-theme]/wp-signup.php$1

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Where do I add the new statements? Thanks.

Any suggestions on where in my .htaccess file to add the new statements? TIA.

Hi @Burlington Avenue,

You can add the provided code before the following line of code in your .htaccess file.

</IfModule>

Also please try adding the following code in your wp-config.php file.

define( 'FORCE_SSL_LOGIN', TRUE );

Thanks, Vinod. Still no change. The page loads with http://.

The file attempts to load with https:// (I see it in address bar) but I get a redirect loop.

Do you have SSL installed and configured for your site? Would you please post an URL of your site?

Cheers

  Yes, I have wildcard SSL that works fine. Rather not post the url, but I have a shopping cart, certain other pages and all subsites that load with https://, as well as login and admin pages. The only problem is with those front-end pages that are core Wordpress. So defining admin and login as true can't touch them, nor using the Wordpress HTTPS to encrypt specific pages.

FYI, both admin and login are defined as true in wp-config.php. I am also using Wordpress HTTPS plugin with Force SSL Admin and Force SSL Exclusively checked.

Hello @Burlington Avenue

If you remove my code and try to visit the signup page using https:// does it load? If it does, please try the following:

# BEGIN WordPress
RedirectMatch 301 ^/blog/([0-9]{4})/([0-9]{2})/([0-9]{2})/([^/]+)/$ http://example.com/$4
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} ^/wp-signup.php?
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]

RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
# redirect to custom signup form
RewriteRule ^wp-signup.php(.*)$ wp-content/themes/[my-theme]/wp-signup.php$1

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

or this one:

# BEGIN WordPress
RedirectMatch 301 ^/blog/([0-9]{4})/([0-9]{2})/([0-9]{2})/([^/]+)/$ http://example.com/$4
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} ^/wp-signup.php?
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]

RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
# redirect to custom signup form
RewriteRule ^wp-signup.php(.*)$ wp-content/themes/[my-theme]/wp-signup.php$1

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Please let me know if it works.

Cheers
