email repeat urgent needed

thank u…

i inserted the script into contact-form-7/includes/capabilities.php
it comes called, because i know it crash on
// $result->invalidate( $tag, “Are you sure this is the correct address?” );
without this line, the rest of the form comes checked, but user get no alert.

everytime it reach above line, the arrow keeps rotating and nothing happen further

ok.. fixed it.. by upgrading WP itself to 4.1
