Configure Https with No Mixed Content

Task Library

Serve the entire site over HTTPS with zero mixed-content warnings so browsers, Google, and visitors trust every page.

Category: Digital Plumbing

Use this when any page shows "Not secure," a broken padlock, or console mixed-content warnings – or when HTTPS has never been verified end-to-end.

Inputs

  • Hosting control panel access (SSL certificate management)
  • WordPress admin access
  • List of key templates to test: homepage, contact page, a service page, a blog post

Steps

  1. Confirm a valid SSL certificate covers both the apex domain and www, and that it auto-renews at the host.
  2. Force HTTPS site-wide: 301-redirect every http:// URL to https:// (host setting or server config). Test by loading the plain http:// version – it must redirect.
  3. In WordPress, set both the WordPress Address and Site Address to https://.
  4. Hunt mixed content: open each key template, check the browser console for mixed-content warnings, and search page source for hard-coded http:// references in images, scripts, stylesheets, and embeds.
  5. Fix offenders at the source – update URLs in content and theme settings (a search-replace on http://yourdomain works for legacy content). Re-check third-party embeds.
  6. Re-test all key templates: full padlock, no warnings, no console errors. Then confirm Google Search Console tracks the https property.

Definition of done (QA checklist)

  • Valid certificate on apex and www, auto-renewing
  • http:// URLs 301-redirect to https:// (tested)
  • Homepage, contact, service page, and a blog post all show the padlock with zero mixed-content console warnings
  • No hard-coded http:// asset references remain in source on tested templates
  • Linked back to the definitive article and relevant siblings
  • Complies with Blog Posting Guidelines (if it publishes content)

Example(s)

  • Example needed – run the Meta-Article Prompt after first real run.
