Title: Fatal error when submitting Formidable Forms form Last modified: February 28, 2024 --- # Fatal error when submitting Formidable Forms form * Resolved [blitton](https://wordpress.org/support/users/blitton/) * (@blitton) * [2 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-when-submitting-formidable-forms-form/) * Hi, * I am using hCaptcha with both WooCommerce and Formidable Forms (free version). It’s working great with WooCommerce, but when I submit the contact form I built with Formidable Forms, I get the following error: * Fatal error: Uncaught TypeError: HCaptcha\FormidableForms\Form::prevent_native_validation(): Argument #2 ($field) must be of type HCaptcha\FormidableForms\stdClass, stdClass given, called in /home/tuscancorp/dev.tuscancorp.com/wp-includes/class-wp-hook. php on line 324 and defined in /home/tuscancorp/dev.tuscancorp.com/wp-content/ plugins/hcaptcha-for-forms-and-more/src/php/FormidableForms/Form.php:135 Stack trace: #0 /home/tuscancorp/dev.tuscancorp.com/wp-includes/class-wp-hook.php(324): HCaptcha\FormidableForms\Form->prevent_native_validation() #1 /home/tuscancorp/ dev.tuscancorp.com/wp-includes/plugin.php(205): WP_Hook->apply_filters() #2 / home/tuscancorp/dev.tuscancorp.com/wp-content/plugins/formidable/classes/models/ fields/FrmFieldCaptcha.php(319): apply_filters() #3 /home/tuscancorp/dev.tuscancorp. com/wp-content/plugins/formidable/classes/models/fields/FrmFieldCaptcha.php(289): FrmFieldCaptcha->should_validate() #4 /home/tuscancorp/dev.tuscancorp.com/wp- content/plugins/formidable/classes/models/FrmEntryValidate.php(217): FrmFieldCaptcha- >validate() #5 /home/tuscancorp/dev.tuscancorp.com/wp-content/plugins/formidable/ classes/models/FrmEntryValidate.php(154): FrmEntryValidate::validate_field_types()# 6 /home/tuscancorp/dev.tuscancorp.com/wp-content/plugins/formidable/classes/models/ FrmEntryValidate.php(37): FrmEntryValidate::validate_field() #7 /home/tuscancorp/ dev.tuscancorp.com/wp-content/plugins/formidable/classes/controllers/FrmEntriesController. php(549): FrmEntryValidate::validate() #8 /home/tuscancorp/dev.tuscancorp.com/ wp-includes/class-wp-hook.php(322): FrmEntriesController::process_entry() #9 / home/tuscancorp/dev.tuscancorp.com/wp-includes/class-wp-hook.php(348): WP_Hook- >apply_filters() #10 /home/tuscancorp/dev.tuscancorp.com/wp-includes/plugin.php( 517): WP_Hook->do_action() #11 /home/tuscancorp/dev.tuscancorp.com/wp-settings. php(665): do_action() #12 /home/tuscancorp/dev.tuscancorp.com/wp-config.php(104): require_once(‘/home/tuscancor…’) #13 /home/tuscancorp/dev.tuscancorp.com/wp-load. php(50): require_once(‘/home/tuscancor…’) #14 /home/tuscancorp/dev.tuscancorp. com/wp-blog-header.php(13): require_once(‘/home/tuscancor…’) #15 /home/tuscancorp/ dev.tuscancorp.com/index.php(17): require(‘/home/tuscancor…’) #16 {main} thrown in /home/tuscancorp/dev.tuscancorp.com/wp-content/plugins/hcaptcha-for-forms- and-more/src/php/FormidableForms/Form.php on line 135 * If I remove the hCaptcha from the form, it submits as expected. I used the Health Check and Troubleshooting plugin with only hCaptcha and Formidable Forms enabled and the Twenty Twenty-One theme to check for plugin conflicts, but the error was the same. * Some info about the website: - WordPress 6.4.3 - PHP 8.1 - hCaptcha 3.9.0 - Formidable Forms 6.8.2 * I’ll be taking this website live tomorrow, so depending on when you see this, the website may be at www rather than dev. I’ve removed hCaptcha from the form for now. * Please let me know if you need any other information to help troubleshoot this issue.
