I need to use gettext in my new application, but when I try to use this
<input type="submit" value='<?php echo _('Enviar'); ?>'>
The Browser show my this legend
ERR_EMPTY_RESPONSE
It didn't show me an error, even when I call a function that doesn't exist, show me this, but if I remove the functions, the form load fine
different factors cause Error net::ERR_EMPTY_RESPONSE, there is no one answer for everyone.
