[BlueOnyx:17741] PHP errors on Disk Usage

[Robert Fitzpatrick]

I have these errors when trying to access disk usage under server 
management on a 5208R VM on a CentOS7/KVM host. Disk usage works fine 
under virtual sites. I found some posts regarding this, but no solution. 
I have done all Yum updates, but not rebooted, logged out and back in, 
the issue remains....

A PHP Error was encountered

Severity: Notice

Message: Undefined index: site2

Fatal error: ob_start() [<a href='ref.outcontrol'>ref.outcontrol</a>]: 
Cannot use output buffering in output buffering display handlers in 
/usr/sausalito/ui/chorizo/ci/system/core/Exceptions.php on line 181

Can anyone suggest how to fix?
