This very simple plugin aims at avoiding mixed content when using https for wordpress sites.
<h4>Principle</h4>
When you are using HTTPS for browsing, all content resources will point to https. All ‘http’ references will be changed to ‘https’.
On the contrary, if you want HTTP browsing, all references will be changed to ‘http’, which can be useful if you are behind a proxy that filters https.

Thanks @janiko for creating this great plugin! It works fantastic on my sites and even your source code looks amazing. Well done!

Simple and yet powerful!

Force http/https for resources, depending on the scheme you use.

It easily solves the problem of mixed unsafe content.
Once a web page has its contents, such as CSS, JavaScript or graphics loads unencrypted, the browser reports the whole website as unsafe.
This message will appear with this or similar texts “Connection is not secure” and “Parts of this page are not secure. This can e.g. be graphics. “.
Now you can check and correct all posts, comments, plugins and the theme …
Or you simply install “SSL Fixit”. 
Finished. There is nothing to configure.
The plugin simply replaces all http: // in the output with https: //.
However, if you still need unencrypted links, you can not use this plugin. 
But that should / should be there in the meantime only in exceptional cases.
