Re: Perspectives, multidomain and multi site issues
Search for plugins and modules realted to calendars in the Plugins List
http://doc.tiki.org/All+Plugins
and the modules list
http://doc.tiki.org/All+modules
There should be some called "events", "upcoming events", "calendar", "calendar_new" (maybe), etc. Many things to look at, and probably not updated documentation about it in the pages about Calendar
Your help is very welcome to have the documentation pages more updated and missinformation fixed! 😉
In addition, you might be interested in using the PluginTrackerCalendar, to get all the power of trackers to display data in a Calendar-type of mode, etc.
