Note: WordPress 3.3 offers a new, non-Flash uploader; this plugin may break it.
If you are using SSL (https) to secure your WordPress admin sessions and you 
have an SSL certificate that is not trusted by default (because it is self- 
signed, signed by an untrusted certificate authority, signed for a different 
domain name, etc.), then you probably have problems using the Flash uploader.
This plugin disables SSL usage by the Flash uploader. This allows you to use 
the Flash uploader when you have FORCE_SSL_ADMIN enabled, with an untrusted SSL 
certificate. This works around the vague “IO Error” you get from the Flash 
uploader in such a situation.
Note that this plugin comes with the following security implications:
<ul>
<li>Flash uploads no longer use SSL, thus, your uploaded files aren’t encrypted 
during transmission.</li>
<li>Uploading files with the Flash uploader will transmit your WordPress 
authentication cookie in plain text.</li>
<li>If someone captures your login cookie (which is transmitted any time you load 
a page on your WordPress site while logged in, whether you are using SSL or 
not), they may be able to use it to upload files, view information about 
uploaded files, or change information about uploaded files.</li>
</ul>
If the benefit of having the Flash uploader available outweighs these potential 
security risks for you, then you can use this plugin to enable the Flash 
uploader.
Note that this plugin override’s WordPress’s auth_redirect and 
wp_validate_auth_cookie functions, and may not work if you are using other 
plugins that override these functions.

NO SSL Flash Upload

Turns off SSL for the Flash uploader when you have FORCE_SSL_ADMIN enabled, in case you are having trouble getting it to work ("IO Error").

<h4>What does this Plugin do?</h4>
With protocol relative url’s you simply leave off the http: or https: part of the resource path. The browser will automatically load the resource using the same protocol that the page was loaded with.
For example, an absolute url may look like
<pre><code>src="http://domain.com/script.js"
</code></pre>
If you were to load this from a https page the script will not be loaded – as non-https resources are not loaded from https pages (for security reasons).
The protocol relative url would look like
<pre><code>src="//domain.com/script.js"
</code></pre>
and would load if the web page was http or https.
Tipp: Check your Settings -> General page and make sure your WordPress Address and Site Address are starting with “https”. 
Add the following two lines in your wp-config.php above the line that​ says “Stop Editing Here”:
<pre><code>define('FORCE_SSL', true);
define('FORCE_SSL_ADMIN',true);
</code></pre>
<h4>What is Mixed Content?</h4>
Mixed content occurs when initial HTML is loaded over a secure HTTPS connection, but other resources (such as images, videos, stylesheets, scripts) are loaded over an insecure HTTP connection. This is called mixed content because both HTTP and HTTPS content are being loaded to display the same page, and the initial request was secure over HTTPS. Modern browsers display warnings about this type of content to indicate to the user that this page contains insecure resources.
Note: You should always protect all of your websites with HTTPS, even if they don’t handle sensitive communications.
<h4>Example</h4>
Without Plugin: 
 src=”http://domain.com/script01.js” 
 src=”https://domain.com/script02.js” 
 src=”//domain.com/script03.js”
With Plugin: 
 src=”//domain.com/script01.js” 
 src=”//domain.com/script02.js” 
 src=”//domain.com/script03.js”
<h4>If using Cache Plugins</h4>
If the plugin isn’t working like expected please purge/clear cache for the changes to take effect!

This is really simple plugin and easy to configure. It works fine and really useful.

Awesome Plugin

A fix for mixed content! This Plugin creates protocol relative urls by removing http + https from links. Works in Front- and Backend!
