First, I'd like to thank Alan and the project team for their continuous effort to improve this module!
Unfortunately, there is an error with the list view of subcalendars in the latest version 3.3.8:
An error has occurred.
Error: List Calendar is currently unavailable.
You can see it on Alan Vance's website if you open the following link in a new(!) browser window:
http://www.avanced.net/DNNEventsModule/ListCalendar/tabid/121/Default.aspx
This error only concernes the List Calendar demo. If you switch to another one of the calendar demos (Default Theme or Small Calendar), it's ok, and if you switch back to the List Calendar, the error is gone! Then close the browser, open it again with the above URL, and you'll see the error again!
I reproduced this on a fresh DNN 4.5.3 installation with the Events 3.3.8 module upgraded from the latest 3.3.8 beta (which was upgraded from Events 3.3.7). There I put an Events module instance in month view on one page, and another module instance in list view on the home page. This second module used the first one as subcalendar.
Then I tried the same on a fresh DNN 4.3.6 installation (if you want to call this version "fresh" ;-) ) and Events 3.3.8 beta (upgraded directly from 3.2), and there it works!
Any ideas?
