E-commerce SSL & Mixed Content Error Fix | Melbourne

We stop browser security warnings and broken assets on your Melbourne e-commerce site so shoppers can complete checkout with a clean padlock. Direct remote diagnosis of SSL certificates, HTTPS redirects, and mixed-content sources—no freelancers, no bidding.

What You'll Get

• Full mixed-content scan - Every insecure image, script, stylesheet, iframe, and font flagged with the exact URL and page it breaks.
• Certificate & chain review - Domain match, intermediate chain, expiry, and SAN coverage checked against your live hostname.
• HTTPS enforcement cleanup - Correct 301/302 paths, HSTS readiness, and canonical URL alignment so carts do not loop.
• Platform-specific fixes - WooCommerce, Shopify custom themes, Magento, and headless storefront asset paths corrected at source.
• CDN & media URL pass - CloudFront, Cloudflare, Bunny, or local media libraries rewritten to HTTPS-safe origins.
• Plain-English handoff - What changed, what to monitor, and a short retest checklist your team can repeat after theme updates.

Serving Melbourne & surrounds

Melbourne e-commerce is a mix of high-street product brands, CBD gift and fashion labels, and industrial-estate fulfilment stores that ship nationally. Certificate mistakes often surface right before a catalogue drop or freight peak when marketing pushes paid traffic to a half-migrated HTTPS build. We work fully remote with optional screen-share walkthroughs for store owners from the inner metro through to outer warehouse belts, including operators near Dandenong logistics corridors when on-call timing matters.

• CBD and laneway retailers needing padlock-clean product and gift pages before weekend footfall and click-and-collect spikes
• Warehouse and wholesale catalogues where CDN-cached HTTP media still leaks into HTTPS category templates after a domain move
• Remote-first delivery with scheduled video sessions that fit Melbourne business hours; on-site only if your stack truly requires local console access

How We Work

1. Step 1: Reach Out - Share your store URL, platform, and what the browser shows (warning text, blocked asset, or failed checkout). We listen first and confirm scope.
2. Step 2: Tailored Plan - Fixed quote for the technical path: single-site patch, full-store sweep, or multi-environment (staging + live) remediation.
3. Step 3: We Deliver - Remote infrastructure work on certificates, redirects, theme/code assets, and CDN rules, with patient plain-language updates as we go.
4. Step 4: Confirm & Follow-up - Joint retest in Chrome/Safari/Firefox, handoff notes, and optional short follow-up window after your next theme or plugin update.

Common Issues & How to Fix Them

These are the patterns we see repeatedly on live Melbourne stores—use the safe checks below before a full engagement.

Padlock broken: active mixed content on product or cart pages

Chrome shows a warning or strips images/scripts because the page is HTTPS but one or more assets still load via http://—common after a partial SSL install or a theme that hard-codes old media URLs.

1. Step 1: Open the page in Chrome, press F12, go to the Console and Security panels, and note every request marked mixed content or blocked.
2. Step 2: In your CMS or theme, replace hardcoded http:// links for images, CSS, and JS with https:// or protocol-relative paths; for WordPress/WooCommerce run a careful search-replace on post content and options only after a backup.
3. Step 3: Hard-refresh, recheck Console/Security, and confirm the padlock is solid with zero mixed-content lines on product, cart, and checkout.

Certificate valid on www but not the apex (or the reverse)

Shoppers hitting the non-covered hostname see NET::ERR_CERT_COMMON_NAME_INVALID even though the other hostname looks fine—frequent when a Melbourne retailer adds a short domain for ads without updating SANs.

1. Step 1: Visit both https://yourdomain.com and https://www.yourdomain.com and compare the certificate viewer (Issued to / Subject Alternative Name list).
2. Step 2: Reissue or expand the certificate so both apex and www (plus any checkout subdomain) are listed; point DNS and server vhost/SNI to the same cert bundle.
3. Step 3: Retest both hostnames in an incognito window and confirm the chain is trusted with no interstitial warning.

Force-HTTPS redirect loop or checkout stuck on HTTP

After enabling “force SSL,” the store bounces between http and https or the cart stays insecure because reverse-proxy, load-balancer, or plugin redirect rules disagree—especially on Cloudflare-fronted Melbourne catalogues.

1. Step 1: Check whether SSL is terminated at the CDN/proxy; note Flexible vs Full vs Full (strict) mode and whether the origin already serves HTTPS.
2. Step 2: Align one source of truth: proxy Full (strict) to an HTTPS origin, disable duplicate force-SSL plugins if the proxy already redirects, and set the store’s base URL to https://.
3. Step 3: Clear CDN cache, test homepage → product → add-to-cart → checkout in a private window, and confirm a single 301 to HTTPS with a stable padlock through payment.

Expert insight (Melbourne scenario): Before a spring catalogue launch we often find “good-looking” certificates that still fail checkout because the payment iframe or a third-party reviews widget was allow-listed on HTTP only in an older CSP or theme partial. A quick Google search tells you to “install SSL”; five-plus years of store rescues teach you to freeze the checkout network waterfall first, map every third-party host, and fix the one insecure script that marketing added last—otherwise you pass the padlock test on the homepage and still lose the sale on pay. Bad looks like a green lock on the home page and a blocked script on /checkout. Good looks like identical secure origins from landing through order confirmation, with HSTS only enabled after that path is clean for a full week.
