sorry to reply you late , i am a little busy those days . and i have find a way to delet it , find the file \zen cart\includes\init_includes\init_header.php and delet the informaiton:
// check if the configure.php file is writeable
if (WARN_CONFIG_WRITEABLE == 'true') {
if ( (file_exists(dirname($_SERVER['SCRIPT_FILENAME']) . '/includes/configure.php')) && (is_writeable(dirname($_SERVER['SCRIPT_FILENAME']) . '/includes/configure.php')) ) {
$messageStack->add('header', WARNING_CONFIG_FILE_WRITEABLE, 'warning');
then everything will be good
IF you haven't changed the file permissions back to 444 then everything IS NOT GOOD.
Just deleting the warning message is not the solution to your problem.
If your configure.php file is set any higher than 444, anyone can hack into your site.
The reason I said contact your host was so they could verify the file permissions were correctly changed to 444. Sometimes you may think you have them changed, but they really aren't.
