the permissions on the WA_CMS/WA_CMS.php are set to none. and using the FTP info you have provided, I am not able to change those permissions.
The permissions level of 755 should be good for directories and 644 should be good for files. The host will need to edit the permissions for that file, as I am not able to.
The CMS Admin username and password you are using is not really very strong. by using weak passwords and a pretty generic username, the CMS system is vulnerable to a brute force attack where a bot basically just tries every combination till it gets in
