How to solve the Permission Error

Question

I have downloaded the minbill project from google code, and tried to run in my wamp server. But its index.php file says error as,

The projects config.php, has

/* Path Information */
//session_save_path:Make sure this is read and writable by the webserver user
$config['session_save_path']    = '/tmp';

//template_cache_dir:Make sure this is read and writable by the webserver user
$config['template_cache_dir']   = '/tmp';

Unchecking is not withstanding in win-7 :

Another problem is, when I unchecked the Read-only button in Window 7 ultimate, it changes, but still Attributes remains as the blue box (as in figure), when i reopen the properties dialog box. But the default attribute is the blue box itself . Hence I do not find fault with that.

Server : I am using Wamp Server. (In that MySQL)

And, I have a directory called /tmp.

Answer 1

Try to write the full path for your /tmp folder.

I see you're in Windows so this should look like C:\your_project\tmp

Answer 2

Start the FTP server of your wamp installation, connect via a ftp client to it, navigate to your /tmp folder and give folder permissions 777 for /tmp and child directories.
