Frequently Asked Questions

Common questions about GridXFlex Captcha Security

No. Code generation, image rendering, and verification all happen on your own server using PHP's built-in GD library. Nothing is sent to any third-party API or service.

For compatibility with page caching and load-balanced hosting. Instead of $_SESSION, each challenge is stored as a short-lived WordPress transient keyed by a random token embedded in the form. This works identically behind full-page cache and across load-balanced PHP-FPM pools without sticky sessions, and every challenge is automatically deleted after a single use.

A hidden form field that's invisible to human visitors but often auto-filled by simple bots. If it's filled in, the submission is rejected the same way a wrong CAPTCHA code would be — no separate "bot detected" message is ever shown, so automated scripts can't learn which check they failed.

No. This version doesn't use any third-party CAPTCHA provider.

Yes. If GD isn't available, the image challenge is automatically skipped — protected forms keep working normally, they just fall back to honeypot-only protection instead of erroring out. You'll see an admin notice explaining this; it clears itself automatically as soon as GD is enabled, no need to reactivate the plugin.

An HTML comment —  — is placed next to the captcha markup wherever it renders (login, registration, lost password, comments). It isn't visible in the page as displayed, only in page source.

They're redirected back to the same post with an inline error message, and their typed name, email, URL, and comment text are restored — nothing is lost and they don't leave the page. Login, Registration, and Lost Password show their errors the same way, inline on the same page, using WordPress core's own error-display mechanism for those forms.
