This is a known bug in the latest osCommerce 060817 release and has to do with the modules not refreshing with udated changes in the admin.
This fix has worked for several users:
1. Open the catalog/admin/includes/functions/compatibility.php.
2. At the end of the “do_magic_quotes_gpc” routine, add the following code
reset($ar);
It will end up looking like this:
function do_magic_quotes_gpc(&$ar) {
if (!is_array($ar)) return false;
while (list($key, $value) = each($ar)) {
if (is_array($ar[$key])) {
do_magic_quotes_gpc($ar[$key]);
} else {
$ar[$key] = addslashes($value);
}
}
reset($ar);
}
3. Do the same for the compatibility.php file located in catalog/includes/functions/compatibility.php.
