How to find and fix mixed content (HTTPS) on any website
Mixed content is when a secure web page (loaded through HTTPS) also contains scripts, styles, images or other linked content that is served through the insecure HTTP protocol.
Luckily, you can use WebSite Auditor (https://seopwr.st/2Os5q7Y) to check any website for mixed content issues:
👉Go to Site Audit / Issues with HTTP/HTTPS site versions
👉Go to Site Audit / HTTPS pages with Mixed Content issues
👉Go to Pages / Custom search and look for issues with the help of CSS selectors:
✔Find rel=canonical tag pointing to HTTP:
link[rel=canonical][href^=http://]
✔Find src attributes pointing to HTTP:
*[src^=http://]
After you fix the found issues, rebuild the project and look though these factors once again.
