Configure fail 2 ban on centos 6 with plesk

Easy project for someone whos a pro. Install fail2ban on centos as per here [login to view URL] So plesk and all ports are covered with email alert with reverse ip look up. Also install fail2ban on xenserver running the install. Both were working before but i edited the setup files and now they are not working. Connection to this server can only be made via teamviewer through my pc for security purposes. We can edit and config together. But [login to view URL] will show the email and ban times etc,
