Moving WordPress from HTTP to HTTPS

Moving WordPress from HTTP to HTTPS encrypts network traffic and consolidates the website on a secure protocol.

It requires more than installing a certificate.

Install and Test the Certificate

The certificate must cover every public hostname and renew reliably.

Test the HTTPS site before forcing redirects.

Change WordPress Address and Site Address to the intended HTTPS URLs.

Confirm login, administration, REST API, cron and media behavior.

Review content, widgets, theme settings, custom fields, CSS, scripts, menus and plugin data.

Use serialization-aware replacement where database values need updating.

Redirect every HTTP path to its HTTPS equivalent.

Avoid redirect chains through alternate hostnames or old domains.

Browsers can block or warn about HTTP images, scripts, styles, fonts and frames loaded by an HTTPS page.

Inspect browser console and network requests across representative templates.

When TLS terminates at a proxy, WordPress must detect the original secure request correctly.

Incorrect proxy headers can cause redirect loops, wrong cookies and HTTP canonical output.

HTTP Strict Transport Security can tell browsers to use HTTPS automatically.

Enable it only after certificates, subdomains and redirects are proven, because long policies are difficult to reverse quickly.

No. It changes the protocol for the same hostname.

It can help rewrite output, but permanent stored URLs and external resources should be corrected at their source.
