Really Simple SSL


Really Simple SSL automatically detects your settings and configures your website to run over https.
To keep it lightweight, the options are kept to a minimum. The entire site will move to SSL.

Three simple steps for setup:

Get an SSL certificate (can’t do that for you, sorry).
Activate this plugin
Enable SSL with one click

Always backup before you go! If you do not have a sound backup policy, start having one! See our recommendations.

Any code suggestions? We’re on GitHub as well!

What does the plugin actually do

The plugin handles most issues that WordPress has with SSL, like when you’re behind a reverse proxy/loadbalancer, or when no headers are passed which WordPress can use to detect SSL.
All incoming requests are redirected to https. Default with an internal WordPress redirect, but you can also enable a .htaccess redirect.
The site url and home url are changed to https.
Your insecure content is fixed by replacing all http:// urls with https://, except hyperlinks to other domains. Dynamically, so no database changes are made (except for the siteurl and homeurl).

Knowledge base

For more detailed explanations and documentation on redirect loops, deactivating, mixed content, errors, and so on, please search the documentation

Does the mixed content fixer make my site slower?

On a site where the source consists of about 60.000 characters, the delay caused by the mixed content fixer is about 0.00188 seconds. If this is too much for you, fix the mixed content manually and deactivate it in the settings.

Uninstalling Really Simple SSL

The plugin checks your certificate before enabling, but if, for example, you migrated the site to a non-ssl environment, you might get locked out of the back-end.
If you can’t deactivate, do not just remove the plugin folder to uninstall! Follow these instructions.

Mixed content issues

Most mixed content issues are caused by urls in css or js files.
For detailed instructions on how to find mixed content read this article.

Redirect loop issues

If you are experiencing redirect loops on your site, try these instructions.

Is the plugin multisite compatible?

Yes. There is a dedicated network settings page where you can switch between network activated SSL and per page SSL. In the dedicated pro for multisite plugin, you can override all site settings for SSL on the network level, and can activate and deactivate SSL in the network menu for each site.* Really Simple SSL maintains an extensive knowledge-base at
