Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

WP PlugIndex currently records Flex SSL version 1.2.1 as active, updated 1mo ago and tested up to WordPress 7.1.
Overview
About this plugin
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_DISABLE in wp-config.php, Tools → Revert URLs, and wp flex-ssl disable / wp flex-ssl revert-urls.
On Multisite, settings and URL updates are per site.
