Well, in the older versions I have similar to your issue which was resolved by 
updating to the latest at that time version.

Yes, I am planning to do so.  Is this fixed in that version?  Do you mind 
explaining what the issue was for future reference?

Thank you for the log location.  With apologies, it happens "consistently" on 
some pages but not constantly everywhere.  It generally occurs on pages that 
are attempting to auto-update.  For instance, it happens on the dashboard home 
page and on the Hosts page when a host is installing and then activating and 
changing statuses on screen.
 
The error log records the following, which is consistent with the property 'a' 
warning seen prior:

Hi Zachary,

I am consistently receiving error warnings in the Administration Portal the 
read as follows:
 
 
 
"Uncaught exception occurred. Please try reloading the page. Details: 
(TypeError) : Cannot read property 'a' of null
   
Please have your administrator check the UI logs"
 

 
 
My questions are:
 
1)  Where/What are the UI logs?
 /var/log/ovirt-engine/ui.log
 
 
2)  Is this a known issue, and how do I fix it?
 

 
 
 
This error doesn't say anything specific to see what is the problem without the 
logs. 
 What does it mean constantly? On all pages?
