Provide a custom URL for the Administration Area.
Specify a unique code for protecting sensitive data, such as user passwords.
Specify a permission mask for folders and files used for installation and software updates.
* If any permission issues occur, then you may use 777 for folder permissions and 666 for file permissions. Setting the folder or file permissions to 777 will mean that anyone can write and/or execute anything in those folders or files. This is not recommended for shared hosting.
