cmsoto, I changed tha declaration of class Transliterator to class Transliterator2 and all correspondent calls.
Already corrected it. Sorry.
I received the following error when tried to download the vCard:
Fatal error: Cannot declare class Transliterator, because the name is already in use in /home/casul975/public_html/wp-content/plugins/team-vcard-generator/includes/VCard.php on line 10
My wordpress version is 4.7.3
