"curl" makes form submission result in 404

Perhaps you were saying something else and I misinterpreted it. You can send me the code and I can test it on my side as well if you want.

It would be interesting if you hacked the show_404() function to print_r() $_POST and $this->uri->uri_string() instead of showing a 404 message. That way we might be able to trace the error. The function should be in system/libraries/Exceptions.php. Just comment out the show_404 function and replace it with something like:

Code:

function show_404($page='')
    {
        echo "Page: <b>$page</b> <br><br>";
        echo "<pre>".print_r($_POST)."</pre>";
        echo '<br>';
        echo $this->uri->uri_string();
        
    }
