i went to Global Configuration then in server tab and i have given the following info Mailer -- SendMail Mail from-- Send Mail Path: /usr/sbin/sendMail SMTP Authentication: No SMTP Host: localhost so i am getting the following error as well An Error has occurred! Unable to open configuration.php file to write! What i have to do
Go to FTP and change the configuration.php file(you will find at root folder) permission and make it 777 and then you will edit that file. Hope it helps...
And once you have done editing configuration.php change the permissions back to at least 644 or your site will be hacked, including your database
