7:48 p.m.
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:

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