You can use like following

add_action( 'fep_form_field_output_file', function( $field, $errors ){
    //Output your file input field here
}, 10, 2);

Hi again,
As CF7 load captcha script in all pages, this may create some conflict in other pages not in CF7 page, because this plugin does not load in CF7 page.
Can you disable captcha in CF7? Just remove keys from CF7 captcha settings. Then see if this working. If you received spam contact messages you can activate https://wordpress.org/plugins/spam-protection-without-captcha/ temporarily which will prevent spam using different approach and will not have any conflict.

Run one or 2 days for testing. Let me know the result.

Thank you.
That is a very good point. I will update you about my finding.
By this time can you give me a screenshot of the settings page of this plugin in your website? You can mask keys.

Use like following

add_action( 'fep_before_form_fields', function( $where ){
    if( in_array( $where, [ 'newmessage', 'reply' ] ) ) {
        echo "This is your sentence";
    }
});

please note for V3 google check so many things in background before determining bot or human. It may be browser cookie/cache or anything which making false positive.

Also in v3 user do not have any option to prove that s/he is human. If it fails, it fails.

I prefer to use v2 so that if it fails user will have option to prove that s/he is human.

Please let me know following.
1. Did you use this plugin before starting this issue?
2. Do you have messages (messages between users) from previous version?
3. Check database and see if there any database table name start with PREFIX_fep_ where PREFIX if your database table prefix. if yes, let me know how many and what are they.
4. Do your set database user in wp-config.php have permission to create database table?

Can you send the website link again.

Ok, I will process your refund.
