Blank page on contact link

Hello

When I try to create a contact link, as shown in the demo (single contact) I get a blank page. I can't find the problem

The site link is http://rutabonsai.com and the contact link http://rutabonsai.com/contacto

Thanks for the help

Hi

Please rise error showing level to maximum (in joomla global configuration) and tell me what error is visible on contact page than.
