Your primary domain is set to: freeadblog.x10hosting.com and is working correctly.
The problem is that your WordPress is configured to work with: smsparaguay.x10hosting.com
The solution would be to change your primary domain to: smsparaguay.x10hosting.com, login to the WP AdminCP, change there the domain that WP is configured to use to: freeadblog.x10hosting.com, and then change your primary domain back to: freeadblog.x10hosting.com.
