Pasion Handball on "i can´t add tags to a post"

I create a new post in http://www.pasionhandball.com.ar and when i want to add a tag, it´s impossible.

The button doesn´t do anything.

I try to add the tags with the "Quick edit" button in the "http://www.pasionhandball.com.ar/wp-admin/edit.php" page, and it does anything too.

I´ve tried deactivating all the plugins, but the error still there.
I´ve replaced by FTP the wp-includes/js folder...

And still happening...

I don´t know what can i do :S

Sorry for my english, and thanks for your help

My WP Theme is: Sixteen
