The latest version of Dreamweaver (2018-01-09) modified common.func.php in the include folder and added two functions.

If the common.func.php file is provided in the downloaded template folder, it is very likely that these two functions are not available, which will cause an error.

You need to paste the code of these two functions into the /include/common.func.php file. The code is as follows:

function make_hash() { $rand = dede_random_bytes(16); $_SESSION['token'] = ($rand === FALSE) ? md5(uniqid(mt_rand(), TRUE)) : bin2hex($rand); return $_SESSION['token']; } function dede_random_bytes($length) { if (empty($length) OR ! ctype_digit((string) $length)) { return FALSE; } if (function_exists('random_bytes')) { try { return random_bytes((int) $length); } catch (Exception $e) { return FALSE; } } if (defined('MCRYPT_DEV_URANDOM') && ($output = mcrypt_create_iv($length, MCRYPT_DEV_URANDOM)) !== FALSE) { return $output; } if (is_readable('/dev/urandom') && ($fp = fopen('/dev/urandom', 'rb')) !== FALSE) { is_php('5.4') && stream_set_chunk_size($fp, $length); $output = fread($fp, $length); fclose($fp); if ($output !== FALSE) { return $output; } } if (function_exists('openssl_random_pseudo_bytes')) { return openssl_random_pseudo_bytes($length); } return FALSE; }

Paste the above code into

/* *

* Load the assistant. The system defaults to loading the assistant

just above this code.
