详情介绍:
Flex SSL is a lightweight WordPress plugin designed to secure your website by enforcing HTTPS across your entire site. Key features include:
- Force HTTPS: Automatically redirect all HTTP requests to HTTPS. Encoded and non-ASCII permalinks are preserved. Alias hosts fall back to the WordPress home URL.
- Auto-Update URLs: Change WordPress site and home URLs from HTTP to HTTPS, with a stored backup you can revert.
- Cloudflare/Proxy Support: Detects HTTPS headers from Cloudflare, Azure, CloudFront, and other reverse proxies to avoid redirect loops.
- Security Headers: Optionally add HSTS (includeSubDomains is optional), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
- Mixed Content Fixer: Rewrites this site’s HTTP URLs to HTTPS in content, excerpts, attachments, srcset, scripts, and styles. External links are left unchanged. Tools can scan the front page for leftovers.
- SSL Status: View certificate expiry, issuer, subject names, trust, and hostname match. Optional admin notices and email before expiry.
- Redirect Options: Choose between 301 (permanent) and 302 (temporary) for GET. Non-GET requests use 307.
- Logs, Tools, and Site Health: Monitor changes, test HTTPS, and see Flex SSL tests in Tools → Site Health.
- Recovery:
FLEX_SSL_DISABLEin wp-config.php, Tools → Revert URLs, andwp flex-ssl disable/wp flex-ssl revert-urls.
安装:
- Upload the
flex-sslfolder to your/wp-content/plugins/directory or install via the WordPress plugin installer. - Activate the plugin through the WordPress admin.
- Navigate to Flex SSL → Settings from the admin menu.
- Confirm the site loads over HTTPS (host panel, Cloudflare Full, or similar).
- Turn on Enable SSL, then Force HTTPS and Update Site URL. Use the proxy override if HTTPS is terminated in front of WordPress.

常见问题:
Does Flex SSL work behind Cloudflare?
Yes. Flex SSL supports reverse proxy configurations including Cloudflare’s Flexible and Full SSL modes by detecting proxy headers. For Flexible SSL, enable “HTTPS is terminated at a proxy” before turning on Force HTTPS.
Do I need to modify wp-config.php?
No. Flex SSL works without wp-config.php changes. If you get locked out, add define( 'FLEX_SSL_DISABLE', true ); to stop all Flex SSL runtime hooks.
How do I generate an SSL certificate?
Flex SSL does not issue certificates. Use your host panel, Cloudflare, or Let’s Encrypt on the server, then use this plugin to enforce HTTPS and watch expiry.
What happens if SSL is not installed on my server?
The plugin checks for a certificate and shows a warning. You can still enable features if HTTPS is terminated at a proxy. Force HTTPS to this origin needs a working certificate.
I cannot reach wp-admin after enabling Force HTTPS.
Add define( 'FLEX_SSL_DISABLE', true ); to wp-config.php, or run wp flex-ssl disable and wp flex-ssl revert-urls. Fix HTTPS, then remove the constant.

- Force HTTPS runs early so wp-admin and wp-login.php are redirected, not only the front end.
- Force SSL Admin uses force_ssl_admin() (the FORCE_SSL_ADMIN constant is already defined before plugins load).
- HSTS is sent only over HTTPS, without preload.
- Mixed content fixer rewrites same-host URLs only, including attachments and srcset.
- Certificate-not-found is a warning, not a lock on the settings.
- Logs record setting changes and rate-limited HTTPS redirects.
- Tested up to WordPress 7.0. Plugin Check cleanup (hidden files, prefixes, sanitization).

- Mixed Content Fixer: Extended to the_excerpt, post_thumbnail_url, script_loader_src, style_loader_src, content_url, home_url.
- Performance: Cache is_ssl_available() result (1 hour transient) to avoid repeated socket connections.
