Force HTTPS (SSL Redirect & Fix Insecure Content)

Description

Redirects all HTTP requests to the HTTPS version and fixes all insecure static resources without altering the database (also works with CloudFlare).

The Long Version

The only Force SSL (HTTPS) plugin that correctly follows Google Chrome team’s advice to avoid protocol-relative hyperlinks and resources. Here are more of the current features:

  • redirects all HTTP requests to HTTPS (domain/protocol 301 redirects)
  • filters all internal resources to become secure (e.g. src=”https://…”)
  • filters all internal hyperlinks to be become secure (e.g. href=”https://…”)
  • filters all external resources to become secure (src, srcset, embeds, and objects)
  • skips any external hyperlinks
  • works with image srcsets too (Version 1.0.2+)
  • no need for additional plugins to fix insecure resources
  • avoids “protocol relative” URLs as recommended by top security experts
  • zero database queries or settings pages
  • huge SEO and security benefits

WARNING: You must have an SSL certificate installed on your server before activating this plugin. If you website becomes inaccessible after activation, login via SFTP and delete this plugin from /wp-content/plugins/ and clear your browser cache.

Compatibility

This plugin has been designed for use on LEMP (Nginx) web servers with PHP 7.0 and MySQL 5.7 to achieve best performance. All of our plugins are meant for single site WordPress installations only; for both performance and security reasons, we highly recommend against using WordPress Multisite for the vast majority of projects.

Code Inspiration

Admin Notices

This plugin generates multiple Admin “Nag” Notices in the WP Admin dashboard. The first one fires during plugin activation which recommends several free plugins that we believe will enhance this plugin’s features; this notice will re-appear once every 6 months as our code and recommendations evolve. The second is a notice that fires a few days after plugin activation which asks for a 5-star rating of this plugin on its WordPress.org profile page. This notice will re-appear once every 9 months. These notices can be dismissed by clicking the (x) symbol in the upper right of the notice box. These notices may annoy or confuse certain users, but are appreciated by the majority of our userbase, who understand that these notices support our free contributions to the WordPress community while providing valuable (free) recommendations for optimizing their website.

If you feel these notices are too annoying, we encourage you to consider one or more of our upcoming premium plugins that combine several free plugin features into a single control panel, or even consider developing your own plugins for WordPress, if supporting free plugin authors is too frustrating for you. A final alternative would be to place the following defined constant in your wp-config.php or functions.php file to manually hide this plugin’s nag notices:

define('DISABLE_NAG_NOTICES', true);

Note: This will only affect the nag notices mentioned above, and will not affect any other notices generated by this plugin or other plugins, such as one-time notices for admin-level users.

  3. Test plugin is working by loading a non-HTTPS version of any page
Does this plugin install SSL for my site?

No. You will first need to order/setup SSL on your server (web host) before activating this plugin.

After installing this plugin, my site is inaccessible?

You probably do not have SSL installed yet on your server (web host) which is a prerequisite.

Are there any potential drawbacks/errors with this plugin?

The only potential error is a 404 error for external resources that do not already support HTTPS.

Does this plugin affect my website’s speed or performance?

No, it should not. It’s very lightweight and should be cached in PHP Opcache and DNS/browser (301s).

My developer installed this for me, is he taking shortcuts?

Mostly likely your developer wants you to be extra protected from insecure resources. This plugin can be (should be) installed as an additional layer of protection/stability even if you already redirect to HTTPS elsewhere (server, CloudFlare, etc). It does not hurt anything to force SSL in multiple places, and in fact provides better redundancy for your security. That said, installing this plugin is not a cure-all and your server (etc) should still be re-configured for SSL too when possible.

What HTTP header codes does this plugin send to browsers?

It generates 301 codes for any http version of any page and redirects to https version of that page.

Does this plugin work with CloudFlare SSL?

Yes, it can be used with CloudFlare’s “flexible” or “full” SSL to avoid “too many redirects” spinning errors.

How can I change this plugin’s settings?

Currenly no settings page exists, but we may add one in future versions.

I have a question or comment, how can I let you know?

Please avoid leaving negative reviews in order to get a feature implemented. Stalking or harassing our team members is also not okay; we will expose those who attempt to extort or threaten us. Instead, you may post on the public WordPress.org forums if you like and other members may be able to help you. Since this is a free plugin, we do not offer support for it; we are also no longer involved at the WordPress.org forums. We recommend joining our Facebook group instead:

Sinnvoll

Das Plugin funktioniert sehr gut für die Umstellung auf SSL. Jetzt läuft alles.

Works like a charm, hasn’t failed me yet!

When you buy an SSL certificate for one of your domains, the hosting company may “install” the SSL for you but that still doesn’t mean your site will load as “https” when someone types your domain name into the address bar. Especially if they happen to type “http”. The hosting company may be so helpful as to tell you that “you need to force https” (really? thanks, but how??) and if they’re REALLY feeling helpful, they may even disclose that you “need to make a change to your .htaccess file” (uh, gee, thanks, i think?) but they don’t help you really at all. Maybe if you’re lucky they’ll send you a help article about how to change your .htaccess file. For that, you’ll need to be comfortable enough with your cPanel (if you even have one) and your web host’s file manager, and a text editor, to do that.

Thankfully instead of all that above, there’s the “Force HTTPS” plugin for WordPress. I’ve used this on several websites now and it works perfectly every time. All you need to do is install the plugin and activate it. BAM. The plugin takes care of all the rest. No need to do any .htaccess file modifications, or even know what that is. If you can install and activate a plugin, you can now force https on your website. You need to wait until SSL is installed. The hosting company generally doesn’t email you the notification that the installation is complete, so once you buy the SSL and they say they’re gonna install it, wait about 24 hours, and type https://your-domain into the browser (change your-domain to your actual domain name of course) and if you see a basic WordPress install complete on your site (the page will load without error, and you’ll see the “secure” padlock in the browser bar), you’re ready to install the plugin. Once you activate it, you’re good to go! Anyone typing your domain into the browser, including if they type “http” it will redirect to “https” and the secure domain. Easy peazy!

Just plug and worked!

amazing plugin, no special settings required, i only installed it and it was done what i wanted, redirected all pages (forced) to HTTPS. Thanks developers!
