website quota (Harddisk) broken after slave server added [vlibTemplate]

Changed my set up from a single machine to master/slave as per this tutorial "https://www.howtoforge.com/installing-a-web-email-and-mysql-database-cluster-on-debian-6.0-with-ispconfig-3"

I used to be able to see quota disk usage but the table has disappeared from the website quota page.

Luckily the values are still being reported on the dashboard

relevant apache2/error.log entry: mod_fcgid: stderr: PHP Warning: vlibTemplate Warning: Invalid loop structure passed to vlibTemplate::setLoop() (loop name: records). in /usr/local/ispconfig/interface/lib/classes/tpl_error.inc.php on line 84,
