[horde] Loading Calendars ......

[HiP-HiPpO]

Last night I found updates to Horde and applications by loading the Horde
admin interface and using the "Check for newer versions" button.  I
upgraded to Horde version 5.2.3.

I had a problem where I would try loading the calendar, I would receive an
empty calendar and along the left hand column would be the message "Loading
Calendars..."  There are no web logs associated with this calendar loading
issue.  I found that running the Rekonq browser on Linux was the only
browser that works correctly.  I tested other current browsers and cleared
all browser caches on Linux (Firefox, Chromium, Konqueror); on OSX
(Firefox, Chrome,Safari); on Windows (Firefox, IE) and all of these would
not load the calendar.

I had hoped that upgrading to 5.2.3 along with upgrading all applications
would have solved this issue.  But it hasn't.
