Try this. Open your Router.php from system/libraries. Around line 146 you should see:
Code:
function _set_request($segments = array())
{
$segments = $this->_validate_request($segments);
add in a debugging line so it says
Code:
function _set_request($segments = array())
{
var_dump($segments);
$segments = $this->_validate_request($segments);
Save that, refresh the page, and see if you get a little bit of text at the top of the page. If so, let us know what exact URL you originally requested and what the output of var_dump is.
