Why am I getting a 'mixed content' warning after moving to HTTPS?

Jul 06, 2025 am 12:52 AM
https Mixed content

Mixed content warnings appear because elements are still loaded over HTTP after the website is migrated to HTTPS. When an HTTPS page refers to an HTTP resource such as an image, script, or stylesheet, the browser is marked as a mixed content, which poses a security risk. There are two types of mixed content: active (such as JavaScript or CSS files, which are usually blocked by the browser) and passive (such as pictures or videos, which are still marked). Common sources include hard-coded HTTP links in HTML, external scripts, CSS background images or fonts, improper settings for CMS or plug-in. Solutions are: 1. Find and replace the "http://" in the code as a relative URL or "https://"; 2. Use browser developer tools to check failed requests; 3. Update CMS settings, plug-ins or themes; 4. Use protocol relative URLs; 5. Ensure that the CDN supports HTTPS; 6. Use WordPress plug-in to automatically handle it. Preventive measures include: setting up HTTP to HTTPS redirection, using CSP headers, checking third-party embedded content, and regularly auditing sites.

You're seeing a "mixed content" warning after moving to HTTPS because some elements on your site are still loading over HTTP. When a page is served over HTTPS but includes resources like images, scripts, or stylesheets from HTTP URLs, browsers flag this as mixed content — a security risk.

Here's how to fix it and why it happens:


What Exactly Is Mixed Content?

Mixed content occurs when a secure HTTPS page pulls in assets using the insecure HTTP protocol. Browsers consider this dangerous because those unencrypted resources could be tampered with during transit.

There are two types:

  • Active mixed content – ??things like JavaScript or CSS files that can manipulate the page. Browsers usually block these outright.
  • Passive mixed content – ??things like images or videos. These are less risky but still flagged.

The result? A warning in the browser console or address bar, and sometimes a broken padlock icon.


Common Sources of Mixed Content Warnings

Some common culprits include:

  • Hardcoded HTTP URLs in HTML or templates (eg, <img src="/static/imghw/default1.png" data-src="http://example.com/image.jpg" class="lazy" alt="Why am I getting a 'mixed content' warning after moving to HTTPS?" > )
  • External scripts or embeds (like ads, tracking pixels, or third-party widgets)
  • CSS background images or fonts loaded via HTTP
  • Incomplete CMS or plugin settings that still use HTTP

Even if your main site is HTTPS, any external resource loaded without HTTPS will trigger a warning.


How to Fix Mixed Content Issues

To resolve these warnings, you need to make sure all resources are pulled in securely. Here's how:

  • Search your code for "http://" and replace them with relative URLs or switch to "https://"
  • Use the browser's developer tools (Network tab) to see which requests are failing due to mixed content
  • Update CMS settings, plugins, or themes that might be pulling in outdated URLs
  • Use protocol-relative URLs (rarely needed now): //example.com/resource.js instead of http://example.com/resource.js
  • If using a CDN, make sure it supports HTTPS and update your links accordingly

Many content management systems like WordPress have plugins that help automate this process (eg, Better Search Replace or Really Simple SSL).


Prevent Future Mixed Content Problems

Once you've fixed existing issues, take steps to avoid new ones:

  • Set up redirects from HTTP to HTTPS
  • Use Content Security Policy (CSP) headers to enforce HTTPS-only resource loading
  • Always check third-party embeds before adding them
  • Regularly audit your site with tools like Google Chrome DevTools or Why No Padlock?

HTTPS is standard now, but it only works if everything on the page plays nicely with it.


It's not complicated once you know where to look, but easy to miss a few straight HTTP links — especially if they come from plugins or embedded content. Fixing mixed content is mostly about attention to detail.

But at the same time, information transmission on the network faces the risk of malicious attacks and theft, so security is particularly important. Based on this, the HTTPS protocol came into being. It is a protocol that adds SSL/TLS encryption to the HTTP protocol to ensure network transmission security. As a language widely used in network development, Java naturally provides a rich API to support the HTTPS protocol. This article will
