WordPress Mixed Content After Migration usually means an HTTPS page still loads one or more resources over insecure HTTP. The safest repair starts by identifying browser mixed-content console entries and where each HTTP URL is generated/stored before changing plugins, code or server settings.
Symptoms
Use the exact symptom and affected URL as the starting point. WordPress Mixed Content After Migration can look similar across sites even when the root cause is completely different.
- Browser shows Not secure or mixed-content warnings on an HTTPS site.
- Images, CSS, JavaScript or fonts are blocked because they use http://.
- The issue began after domain migration or enabling SSL.
- Some URLs are fixed while theme/plugin-generated assets still use HTTP.
Common causes
The main areas to investigate are old database URLs, hard-coded theme/plugin assets, CSS URLs, CDN configuration, serialized data or proxy/site URL mismatch. A good diagnosis narrows these possibilities with logs and request-level evidence instead of changing multiple systems at once.
- Old HTTP URLs remain in WordPress content/options/metadata.
- Theme/plugin files hard-code the previous HTTP URL.
- Generated CSS/cache contains stale HTTP references.
- CDN/media URLs are configured with HTTP.
- WordPress/proxy URL detection still believes requests are HTTP.
Safe diagnosis
- Use browser console to list the exact insecure resource URLs.
- Determine whether each URL comes from database content, generated CSS, theme/plugin code or CDN.
- Verify WordPress/Site Address and proxy HTTPS detection.
- Search/replace database values only with serialization-safe tooling and backups.
Production safety: Create a current backup or recovery point before changing code, database values, plugins, PHP, rewrite rules or server configuration. On WooCommerce and lead-generation sites, test disruptive changes in staging whenever possible.
How the issue is fixed
- Correct WordPress/site/CDN HTTPS configuration.
- Replace stored HTTP URLs safely and regenerate derived CSS/cache.
- Fix hard-coded theme/plugin asset URLs.
- Retest all templates and checkout/forms for mixed resources.
What to avoid
Avoid this shortcut: Do not run a blind raw SQL search/replace across serialized WordPress data. Use serialization-aware tooling or you can corrupt options and widget/plugin settings.
When expert troubleshooting makes sense
If wordpress mixed content after migration is affecting revenue, wp-admin access, publishing, checkout, forms or a live campaign, the priority is a reversible fix with a documented root cause. WP•FIX separates ordinary software faults from security incidents, so suspicious redirects, unknown administrators or injected code are handled through the malware-response path instead of being treated as a normal bug.
FAQ
What usually causes WordPress Mixed Content After Migration?
Common causes include old database URLs, hard-coded theme/plugin assets, CSS URLs, CDN configuration, serialized data or proxy/site URL mismatch. The visible symptom alone is not enough to identify which one is responsible.
Can WordPress Mixed Content After Migration be fixed without wp-admin?
Often yes. Hosting logs, SFTP/SSH, database tools, browser developer tools or the hosting control panel can provide enough evidence when wp-admin is unavailable.
Should I disable every plugin to fix WordPress Mixed Content After Migration?
A full plugin shutdown can be useful as a controlled test, but on a live business site it can create new failures. It is safer to collect evidence and isolate the likely component with a reversible plan.
When should I request professional WordPress troubleshooting?
If the site is down, checkout or lead generation is affected, the error returns after a temporary workaround, or the cause is unclear from logs, a targeted diagnosis reduces risky trial-and-error.
