What is Forminator plugin?
Forminator is a free WordPress form builder from WPMU DEV. Unlike most plugins in this category, Forminator includes quizzes, polls, and calculators alongside standard forms — making it one of the most versatile free interactive content tools available for WordPress. The free version at WordPress.org is notably generous, covering contact forms, multi-page forms, conditional logic, email notifications, and basic payment processing via Stripe and PayPal.
The plugin has over one million active installations and a 4.6-star rating at WordPress.org. It integrates with 25+ platforms including Mailchimp, HubSpot, ActiveCampaign, Slack, Google Drive, and others. The Stripe and PayPal integrations are available in the free version for basic payment collection, which is unusual compared to competitors where payments are exclusively a paid feature.
Forminator is part of WPMU DEV’s broader plugin and hosting ecosystem. The full Forminator experience is enhanced when used with a WPMU DEV membership, which bundles multiple premium WordPress plugins and managed hosting. However, the free standalone plugin is fully functional for most common use cases without a membership. For teams that want quizzes and polls alongside forms without a separate plugin, Forminator eliminates that need.

Common Problems & Fixes
Why are Forminator form submissions not triggering email notifications?
Forminator emails go through WordPress wp_mail(). If notifications are missing, configure an SMTP plugin to route email through a reliable provider. Forminator Settings → Emails also lets you set a test email and verify the configuration. Check that the notification is configured with a valid “to” address and that no conditional logic on the notification is preventing it from firing.
Why is Forminator Stripe payment not processing?
Stripe payment failures in Forminator usually come from API key configuration errors, JavaScript conflicts preventing the Stripe Elements from loading, or the form not having a payment field correctly connected to the Stripe integration. Check the browser console for JavaScript errors when the payment form loads. Verify in Forminator → Settings → Integrations that the Stripe API keys are correct and in the right mode (test vs live).
Why are Forminator quizzes not calculating scores correctly?
Quiz score errors usually result from incorrect answer point assignments in the quiz editor. Each quiz question has correct/incorrect point values that you set during quiz creation. Revisit the quiz editor, confirm each answer has the intended score value, and test the quiz end-to-end in a browser. Also check whether conditional logic on the quiz is routing some questions incorrectly.
Customization & Developer Notes
How do I style a Forminator form to match my theme?
Forminator has a built-in Design section in each form’s settings where you can set colors, font sizes, and border styles visually without CSS. For deeper control, target .forminator-container and its child classes in your theme stylesheet.
Can I embed a Forminator quiz in a page built with Elementor or Divi?
Yes. Forminator provides a shortcode for every form, quiz, and poll it creates. Use that shortcode in Elementor’s Shortcode widget, Divi’s Code module, or any block that accepts shortcodes. Forminator also has dedicated Elementor and Gutenberg blocks for more integrated embedding.
Frequently Asked Questions
Does Forminator include a calculator feature?
Yes. Forminator includes a Calculator form type that lets you build forms with calculation logic — price estimators, loan calculators, BMI calculators, and similar tools. Field values feed into formulas that display a calculated result to the user.
Is Forminator completely free?
The core plugin at WordPress.org is entirely free, including Stripe/PayPal payment forms, quizzes, polls, and most integrations. WPMU DEV membership adds priority support and access to additional plugins, but the free standalone plugin is fully functional.
How many form types does Forminator include?
Forminator covers four main types: contact forms (data collection with email notifications and entries), quizzes (knowledge-check or personality quizzes with scoring), polls (single-question voting), and calculators (formula-based interactive tools). This breadth in a single free plugin is one of its main differentiating factors.
Does Forminator work with the block editor?
Yes. Forminator has a dedicated Gutenberg block that lets you embed any form, quiz, or poll directly in block editor content without a shortcode.
