cPanel --> FileManager --> the directory in question --> .htaccess file
Open .htaccess
Look for lines something like
Code:
AuthName "xampp user"
AuthType Basic
AuthUserFile "C:\xampp\security\xampp.users"
require valid-user
Put a # in front of each such line (instead of deleting them --- in case you want to re-enable the password protection later)
Save .htaccess
Check directory from web browser -- clear browser cache and history first.
