In short

A mixed content warning shows up when a page loads over HTTPS but calls in an image, script, or stylesheet from an http:// address, so the browser will not mark the connection as fully secure. Fix it by setting the WordPress and site URLs to https://, running a database search-and-replace to swap stored http:// links for https://, and correcting any hardcoded http references left in theme files, widgets, or page builder content.

You installed an SSL certificate, the site loads at https://, and the padlock still shows a warning icon instead of a clean lock. Click it and the browser lists the culprit: 'This page includes other resources which are not secure.' It's one of the most common support tickets right after a domain moves from http to https, and it rarely means the certificate itself is broken.

WordPress stores full URLs, not just file paths, inside post content, widget settings, theme options, and the wp_options table. When a site is only switched to SSL at the server level, every one of those saved http:// references stays exactly as it was, and the browser flags each one it finds. Clearing the warning means finding and updating those references at the database level, not just reissuing the certificate.

Why the Padlock Still Shows a Warning After Adding SSL

Browsers grade a page as fully secure only if every single resource on it, down to the smallest tracking pixel or embedded font, loads over HTTPS. If even one script tag or background-image reference still points to http://, Chrome and Firefox downgrade the padlock and show a warning rather than treating the certificate as pointless.

This is separate from whether the SSL certificate itself is valid. A brand-new, correctly issued certificate with free auto-renewal will still trigger the warning if old content on the page references insecure URLs, which is why simply reinstalling or renewing the certificate never resolves this on its own.

Finding Every Source of Insecure Content

Open the padlock icon in the browser address bar and view the security details, which usually list the exact insecure URLs being blocked or loaded. Then check the page's HTML source (Ctrl+U) and search for http:// to spot leftover references in image tags, embedded video players, or inline scripts added by a theme or plugin.

Common offenders include images uploaded before the SSL switch, font or analytics snippets pasted with a hardcoded http:// prefix, favicon and logo URLs set in theme customizer fields, and old video or social embeds saved with their original http link.

Running a Safe Database Search-and-Replace

Because WordPress serializes some data, such as widget settings and theme options, as PHP arrays with string-length prefixes, a plain find-and-replace in phpMyAdmin can corrupt those rows. Use a serialization-safe search-and-replace tool, or a plugin built for the job, and always take a full database backup before running it.

Run the replace searching for http://yourdomain.com and replacing with https://yourdomain.com across all tables, then check the homepage, a blog post with images, and any page built with a page builder to confirm nothing broke. Daily backups mean a bad replace is never more than a restore away from being undone.

Cleaning Up Hardcoded Links in Themes and Widgets

A database replace won't catch links typed directly into a theme's PHP files, a custom HTML widget, or a header script inserted through a plugin. Search theme files for 'http://' in a code editor, and check any custom CSS, header or footer scripts, and menu items built with manually entered URLs.

Once the database and hardcoded references are both clean, add a redirect from http to https at the server level and confirm the site loads over HTTPS by default. A one-click installer environment with a properly configured control panel makes it straightforward to check redirect rules without digging through raw config files.

How to Fix Mixed Content Warnings in WordPress

SSL That's Set Up Correctly From Day One

Most mixed content problems trace back to a certificate that was added after the site was built, leaving years of saved http:// links behind. Hosting with SSL issued and configured automatically at signup, before content is created, avoids that whole class of cleanup later.

Free auto-renewing SSL means there's no certificate expiry to track and no manual reinstallation step that could reset URL settings, so the padlock stays clean without repeat maintenance.

How It Works

Get set up in a few steps

Locate the insecure resource

Use the browser's padlock details and page source to find the exact http:// image, script, or link triggering the warning.

Search-and-replace the database

Back up the database, then use a serialization-safe tool to swap stored http:// URLs for https:// across all tables.

Fix hardcoded links and force HTTPS

Update any http:// references typed directly into theme files or widgets, then set a site-wide redirect to https://.

FAQ

Frequently asked questions

What exactly causes a mixed content warning?

It happens when an HTTPS page loads at least one resource, such as an image, script, or stylesheet, from a plain http:// address instead of https://. The browser considers the overall connection only partially secure and shows a warning instead of a full padlock.

Will renewing my SSL certificate fix a mixed content warning?

No. The certificate secures the connection itself; the warning is caused by content saved with old http:// links. Renewing or reissuing the certificate does not change any of that stored content, so the warning stays until the links are updated.

Is it safe to fix this with a plain find-and-replace in phpMyAdmin?

Not directly. WordPress serializes some settings with string-length counts, and a plain text replace can break those rows if the new text is a different length. Use a serialization-aware search-and-replace tool and back up the database first.

Why do images still show as insecure after I updated my posts?

Older image URLs are often stored in multiple places, including post content, image metadata, and cached page builder data, so a single edit in the visual editor may miss copies saved elsewhere in the database.

Do I need a plugin to fix mixed content warnings?

A plugin isn't required, but a dedicated search-and-replace tool makes the database step much safer than editing tables by hand, especially on a site with years of accumulated content.

How can I stop this from happening again?

Set up SSL and force HTTPS before adding content to a new site, always enter new links as https://, and take a backup before any bulk content change so a future fix is a quick restore rather than a rebuild.
