Good night. in advance thank for your support. I have added an attachment in the next item: www.zacapumich.mx/index.php/noticias/item/52-concurso-de-canto-aficionado-de-musica-mexicana-2015
it simply does not displayed. I can see the atachment in my backend, but in the frontend, nothing. I configured the category for show it, permissions, disable extension, and still is not working. I m working with Joomla 3.4 and K2 2.6.9

why it is happening?

Hi,

Perhaps the attachment code block is not present in your item.php file. If you're using template override, try using k2 default template and see of the attachment shows.

Double check the category's settings as well to see if you have enabled the attachments.
