Calendar installed but not working [#2679793]

I'm trying to set up the Calendar module in my latest multisite sandbox but so far the calendar is not functional at all. Two previous sites on the multisite have functional calendars using the same installed module (in sites/all/modules). With the new site I'm getting these two error messages:

Warning: Creating default object from empty value in calendar_plugin_row->pre_render() (line 312 of /var/www/cifs/ndgsd1dev/sites/all/modules/calendar/includes/calendar_plugin_row.inc).

Debug:
'calendar_plugin_style: A date argument is required when using the calendar style, but it is missing or is not using the default date.'
in calendar_plugin_style->render() (line 238 of /var/www/cifs/ndgsd1dev/sites/all/modules/calendar/includes/calendar_plugin_style.inc).

----

I have tried to match the configuration settings 1:1 but still no luck. When I try to alter settings in the calendar View such as:

Format
Format:Calendar | Settings
Show:Calendar Entities | Settings

as soon as I save, I get a page full of ajax screen dump. I can hit the back button and the change seems to save, it's just very unusual to see this kind of data dump and it must indicate something.

I will keep investigating and post the solution when I find it. Please help if you see any clues.

I made sure I was using the jquery settings I used on my other sites: 1.9 for default and 1.7 for admin. Then, the breakthrough came when I create a few, this time creating it "from templates". There I selected a readymade calendar template and that seemed to work.

I hope this helps somebody else too. Create calendar views from calendar view templates!
