You got this error when try to download a file with rapidleech?
Value for $secretkey is empty, please create a random one (56 chars max) in accounts.php!
Don't worry, :D you can fix it...
open : configs/accounts.php on your rapidleech folder
replace this line : $secretkey = '';
with this one : $secretkey = 'secrettt';
you can change secrettt with anything you like :D
