Hi Richard,
Yes, I tested for problems caused by the Plugins, proved negative. And a change in the theme exhibited a problem, but it was different in that it went to a blank page vs just not changing.
Further, I’d like to update to the latest version, but the auto-update feature is not there and if I download it and install that way it complains that the directory exists and stops the installation.
As far as the link I provided goes, it is what IE has in the address bar when I’m on the calendar page, cut and pasted below.
