v1.5.6.1 - Syntax errors in "catalog\controller\error\not_found.php"

[villagedefrance]

To avoid an error being returned in the log, these lines needs to be corrected:

Error 1: class controllererrornotfound extends controller {
Change to: class ControllerErrorNotFound extends Controller {

Error 2: $this->response->addheader($this->request->server['server_protocol'] . '/1.1 404 not found');
Change to: $this->response->addHeader($this->request->server['SERVER_PROTOCOL'] . '/1.1 404 Not Found');

Error 3: if (file_exists(dir_template . $this->config->get('config_template') . '/template/error/not_found.tpl')) {
Change to: if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/error/not_found.tpl')) {

This is already fixed in v2.0
