<blockquote>
<p><strong>Remove HTTP</strong> is a plugin that automatically scans and removes both <code>http:</code> and <code>https:</code> protocols from all links. This helps resolve websites that are having “<a href="https://wordpress.org/plugins/remove-http/faq/" rel="ugc">mixed content warnings</a>” which is when the website has assets (images, JavaScript, and CSS) loading both HTTP and HTTPS.</p>
</blockquote>
<p>No changes to the links are made in the database. Simply install and activate the plugin and the changes will be immediate. Links that have <code>http://</code> or <code>https://</code> will only have <code>//</code>, making them protocol relative URLs. Below is a before and after example.</p>
<h4>Before</h4>
<pre><code><link rel='stylesheet' href='https://example.com/style.css' type='text/css' />
<script type='text/javascript' src='http://example.com/script.js'></script>
<a href="https://example.com" title="Example">Example</a>
<img src="http://example.com/image.jpg" width="150" height="50" />
</code></pre>
<h4>After</h4>
<pre><code><link rel='stylesheet' href='//example.com/style.css' type='text/css' />
<script type='text/javascript' src='//example.com/script.js'></script>
<a href="//example.com" title="Example">Example</a>
<img src="//example.com/image.jpg" width="150" height="50" />
</code></pre>
<h4>Switch to Relative URLs</h4>
<p>There is an option (under the <em>General</em> settings) to change internal links to relative URLs.</p>
