    Contact Form 7 v3.7.2's admin/includes/meta-boxes.php doesn't have any 'validation_error' in its code. Maybe you have changed the code or you're using different plugin.

    I didn't changed that file, and in my meta-boxes.php there is no 'validation_error' string too.

    But, if you look at the line 97 there is a code:
    <input type="text" id="<?php echo $field_name; ?>" name="<?php echo $field_name; ?>" class="wide" size="70" value="<?php echo esc_attr( $post->messages[$key] ); ?>" />

    This 'validation-error' is a one of those $key.
    I have had many other same error messages about that illegal offset as:
    number too large, date too early, upload failed...

    These messages also appear in the contact form back office in last part called "Messages"
