One of my users is suffering from Calendar problems.
At any time, the Calendar overview looks correct upon logging in. The dates with events are marked as bold.
However, the moment the date with an event is clicked, all the dates are no longer in bold and the event details are not listed.
It only goes back to normal if the user does a full browser refresh.
Nothing in the log file seems to suggest anything wrong.
The issue just appeared out of no where on one fine day.
The user is using Firefox 126.96.36.199.
