202614 releases

  1. SSL Zen 4.7.43Latest

    • Security: fixed a reflected XSS in the setup message handler (the uri/host request values are now escaped on construction and output) and a path-traversal / arbitrary-file-read in the certificate-file AJAX handler (now capability-gated and constrained to the keys directory). Reported by Wordfence.…

  2. SSL Zen 4.7.42

    • Dashboard: the “More from Zen Plugins” panel now recommends 404Zen — our free broken-link & 404 checker that grades your whole site — with a direct link to it on WordPress.org.

  3. SSL Zen 4.7.41

    • Added an optional email opt-in during setup (Step 1) and on the SSL-activated success screen — get a reminder before your certificate expires so your site never slips back to “Not Secure”, plus occasional SSL tips. Unchecked by default, one-click unsubscribe.

  4. SSL Zen 4.7.40

    • Security hardening: certificate, private key, status and debug-log downloads now require administrator privileges and a valid security nonce (fixes a report where the setup-file download handler ran without an explicit capability/nonce check)

  5. SSL Zen 4.7.39

    • Added anonymous, opt-in setup analytics so we can see where users get stuck during SSL setup and make it smoother (first-party only, no personal data, respects your tracking-consent choice)

  6. SSL Zen 4.7.38

    • Simplified the post-setup screen: one friendly, no-pressure review request shown to everyone, with a help option always available

  7. SSL Zen 4.7.37

    • Redesigned the upgrade screen: a clearer good-better-best choice (annual, a pay-once lifetime option, and a done-for-you setup) with a simple side-by-side of what changes when you go Pro

  8. SSL Zen 4.7.36

    • Fixed a gap between the HTTP verification tab and its card (only DNS connected before)
    • Paying customers no longer see the ‘Upgrade to Pro’ bar (gated on the license, matching the plan badge)

  9. SSL Zen 4.7.33

    • Step 2: the HTTP/DNS tabs now connect flush to the verification card instead of floating above it
    • Tidied the Debug log box and the Download button spacing/alignment
    • The Upgrade bar now opens the pricing/comparison page (which explains the plan first) instead of jumping straight to checkout

  10. SSL Zen 4.7.31

    • Fixed the upgrade bar sitting slightly left of the rest of the page — it now lines up flush with the header and setup steps

  11. SSL Zen 4.7.14

    • Fixed: paying customers running the free build now correctly show as “Premium” and see a clear prompt to activate the Pro version — resolves the recurring “I upgraded but it still shows Free” issue.
    • Improved: cPanel SSL installation reliability — raised the API timeout that caused “install_ssl did not return valid JSON” failures, added diagnostic logging, and fixed an error in the failure path.
    • Improved: Step 2 now advances automatically after a successful domain verification instead of appearing to stall.
    • Improved: clearer, less alarming wording for the 301 .htaccess redirect option.

  12. SSL Zen 4.7.13

    • New: self-serve account controls on the Settings screen — re-check your license in one click if you upgraded but the plugin still shows “Free”, and manage or cancel your subscription (including turning off auto-renewal) yourself, without contacting support.

  13. SSL Zen 4.7.12

    • Fixed: the version shown on the SSL Zen screen was stale (an internal version number wasn’t updated with releases). It now always reflects the installed version, and plugin styles/scripts refresh correctly on update.
    • New: a redesigned success screen after your certificate installs — it confirms your site is secured with a one-click verify link, and only asks happy users for a WordPress.org review (users who hit a snag are routed straight to help instead).
    • New: a friendlier, SSL Zen-branded in-plugin help widget that searches our full guide library for instant answers, and — when you message us — automatically attaches your site details so we can help faster.

  14. SSL Zen 4.7.8

    • Critical fix: setup wizard fatal error on Step 2 (and Step 4 / Settings) caused by a malformed esc_html_e() call — this was breaking SSL certificate installation for free-tier users on PHP 8+
    • Fixed PHP warnings (undefined array key ‘contact’ / ‘initialIp’) in the Let’s Encrypt account handler
    • Verified compatibility with WordPress 7.0 (full certificate issuance and HTTPS activation tested end-to-end)
