Fixing WordPress mixed content issues
When you visit a site using https:// your browser will expect all the content to be sent securely, over SSL - which is what gives you https (HTTP Secure) and the green padlock.
However, sometimes some content from the site or page will be sent over http:// - and this will cause a mixed content warning. How you see this varies by browser, some show a warning, others an orange padlock (instead of green) and others just don't show the content.
This is something you'll want to resolve to ensure all visitors have a secure visit and optimal experience. There are a number of options:
- Use this handy website to scan your site and advise you exactly which content is being sent insecurely - you can then edit those posts or pages to update the links to https:// - Why No Padlock.
- If there are simply too many insecure links to enable you to change them all quickly you could use a plug-in like Really Simple SSL to ensure all content is served over https://
- Use a WordPress plug-in like Better Search and Replace to change all occurrences of http://<your-website-domain> with https://<your-website-domain>
