FAQ
-
Which forms are supported for free?
-
Contact Form 7, WPForms, and Formidable Forms. Every other integration (Gravity Forms, Elementor Pro, WooCommerce, WordPress login/comments, etc.) is part of MultiForm Anti-Spam Image CAPTCHA Pro.
-
Can I customize the icons, colors, or messages?
-
Not in the free version. All customization controls—including icon selection, colors, layout, AJAX toggles, and error text—are unlocked in Pro.
-
Is the CAPTCHA accessible?
-
Yes. The challenge uses keyboard-friendly radio buttons, clear on-page instructions, and ARIA labels. Audio prompts and deeper accessibility tuning are part of the Pro version.
-
Does it work with caching plugins and CDNs?
-
Yes. Validation runs server-side and submission keys expire automatically, so cached pages continue to work normally.
-
Can I use it alongside reCAPTCHA or other spam blockers?
-
Absolutely. MultiForm Anti-Spam Image CAPTCHA works independently and adds another validation layer alongside tools like reCAPTCHA or Akismet.
-
How is this different from static answer” icon CAPTCHAs?
-
Every challenge generates a unique key, hashes the correct icon with your site salt, and stores it in the database. Bots can’t scrape the answer from the markup, and stale keys are purged daily to prevent replay attacks.
-
Does the plugin support WPML?
-
Yes, both the free and pro versions support WPML.
