Fix Mixed Content (HTTPS) Warning

The Problem

Your site has SSL installed and shows as HTTPS, but the browser still shows a "not fully secure" warning because some resources (images, scripts, stylesheets) are still being loaded over plain HTTP.

About this problem

Mixed content happens when a page loaded securely over HTTPS still references some resources over the old, insecure HTTP protocol — often leftover hardcoded links from before SSL was added, or a theme/plugin/third-party embed that wasn't updated along with the rest of the site. Browsers flag this because insecure resources on an otherwise secure page create a genuine gap an attacker could exploit, even if it looks like a minor cosmetic warning.

This is extremely common right after adding SSL to a site that previously ran on HTTP, since old content, databases, and configuration files often still reference the old protocol explicitly.

What's Included

• Scanning the site to find every HTTP resource being loaded on HTTPS pages
• Fixing hardcoded HTTP references in code, content, and database where relevant
• Checking third-party embeds/plugins for ones still forcing HTTP
• Verifying a clean, warning-free padlock across the site afterwards

What's NOT Included

• Fixing third-party embeds that have no HTTPS option at all (flagged, with alternatives suggested if relevant)
• Content rewrites beyond correcting the protocol of existing links/resources
• Ongoing content audits as new content is added (this fixes the current state)

How It Works

1. Scan the site's pages for mixed-content warnings, identifying every HTTP resource loaded on an HTTPS page.
2. Check whether the issue is hardcoded URLs in theme/template code, in page content/database, or from a third-party script.
3. Update hardcoded references to use HTTPS (or protocol-relative URLs where appropriate).
4. For database-stored content (common in WordPress), run a careful search-and-replace rather than editing every page individually.
5. Re-scan every key page to confirm zero remaining mixed-content warnings and a clean padlock.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

What does 'mixed content' mean?

It means a page loaded securely over HTTPS is still pulling in some resources (images, scripts, styles) over the old insecure HTTP protocol, which browsers flag as a security gap.

Why do I still see a warning even though my site has SSL?

Having an SSL certificate only secures the main page connection — any individual resource still linked via plain http:// will still trigger a mixed-content warning.

Can mixed content break my website's functionality, not just show a warning?

Yes, in stricter cases (particularly scripts) browsers block the insecure resource entirely, which can break page functionality, not just show a warning icon.

How do I find mixed content on my own site?

Browser developer tools show mixed-content warnings in the console, though a dedicated scan across every page is more thorough than checking manually one by one.

Does mixed content affect SEO?

It can indirectly, since Google treats the page as not fully secure, and visitors bouncing due to the warning also sends a negative signal.

Will fixing mixed content break any of my existing content or links?

No, when done carefully (correct search-and-replace, checking before and after), existing content and links stay intact — only the protocol (http to https) actually changes.
