I have a content type with a machine name of 'empresas' after reading the documentation I should be able to just create a node--empresas.tpl.php to toy with the output of this in my theme.
it seems to be not overwriting it. I am trying to hack something together and I am using the twitter bootstrap Drupal theme.
I have seem a similiar problem into another post in this forum but it seems like taht is not may problem because he have solve it by clearen all the cache's but that was not my case.
