Template Library Version 1.4.1

Ok. So in that case all CI libraries are loaded, and it works.

But if you request a URL that can't be routed, the bootstrap will call show_404() directly. If that happens the Exception class (including your extension) is loaded without autoload being executed, in which case you won't have the CI libraries loaded.

A quick check shows that the Template library uses the Loader class to load additional libraries and helpers. This is not available when you're in a "URL can not be routed" situation. So make sure you test that, and deal with any issues.

Back to the issue at hand: the render() method of the Template library will write the output to CI's output class, in the assumption that will be used to process the output and send it to the browser.

In this case you don't want that, you want to echo it out. So use this:

Code:

function show_404($page = '', $log_error = TRUE) {
    $this->ci =& get_instance();
    $this->ci->template->set_master_template( 'template' );
    echo $this->ci->template->render(NULL, TRUE);
    exit;
}
