No SSL was detected
If you see this message at the top of your page, this can mean two things:
- You don’t have an SSL certificate. You can check this on ssllabs.com/ssltest
- The certificate check in Really Simple SSL failed, because the output on yours server differs from the expected output.
If the scan on SSL Labs checks out, you can get Really Simple SSL to detect SSL simply by loading the admin over SSL:
- Go to the login page of your site on https, e.g.: https://domain.com/wp-login.php, and login
- Your site layout might break, but don’t worry. This is because the stylesheets are not SSL yet.
- Look for the button “enable SSL” (you might have to scroll down a bit if it’s broken), and click it.
That’s it! Your site will now be configured for SSL.
An alternative method, if the above does not work, is to force the plugin to activate by adding
to your wp-config.php. Please note that if your site does not load properly over https because of server configuration issues, this might cause problems. Be careful with this option.
If SSL was detected, but you’re seeing this message after activation: to change this page upload a new index.html to your private_html folder or something similar, pease check out the link for the article on this topic.
Edge case: test page couldn’t be opened and no server variables
There are some cases in which the test page could not be opened by the plugin, and when you check it manually: https://your-domain.com/wp-content/plugins/really-simple-ssl/ssl-test-page.php
It returns this:
#NO KNOWN SSL CONFIGURATION DETECTED#
(make sure you have https in the url!)
In these cases, even if you load your site over https, it will still return “no SSL detected”. In that case, you need to “force” WordPress to see it is on SSL. You can do this by adding
$_SERVER[“https”] = “on”;
To your wp-config.php. Normally Really Simple SSL does this, but if the testpage couldn’t be opened, it won’t do this automatically.
