Hi Jair,

Thanks for your response. I understand that Forminator uses the built email delivery configuration in WordPress which is why I ruled this out before contacting you. I use an SMTP plugin which delivers other email from WooCommerce and other plugins.

I included the error log in my original post which shows where Forminator is failing with a fatal error upon sending. As a quick fix to get around it, I edited the function to be the below instead. But I do not know why the $value is null when a string is expected. After my quick fix, Forminator sends the email notifications successfully.

File: /wp-content/plugins/forminator/library/helpers/helper-fields.php

Original:

function forminator_replace_placeholder_in_urls( string $content, string $placeholder, string $value ): string {
	$value   = rawurlencode( $value );
	$pattern = '#https?://[^\s"\'<>()]*' . preg_quote( $placeholder, '#' ) . '[^\s"\'<>()]*#i';

	return preg_replace_callback(
		$pattern,
		static function ( $matches ) use ( $placeholder, $value ) {
			return str_replace( $placeholder, $value, $matches[0] );
		},
		$content
	);
}

Edited:

function forminator_replace_placeholder_in_urls( string $content, string $placeholder, ?string $value ): string {
    $value = rawurlencode( $value ?? '' );
    $pattern = '#https?://[^\s"\'<>()]*' . preg_quote( $placeholder, '#' ) . '[^\s"\'<>()]*#i';

    return preg_replace_callback(
        $pattern,
        static function ( $matches ) use ( $placeholder, $value ) {
            return str_replace( $placeholder, $value, $matches[0] );
        },
        $content
    );
}
