[Plugin: Upcoming] Function call error in sidebar widget

When installing this plugin and adding the Upcoming widget, I encountered the following error when saving changes:

Fatal error: Call to undefined function get_upcoming_events() in ...\wp-content\plugins\upcoming\upcoming.php on line 236

I searched and could not find the get_upcoming_events() function anywhere.

So I changed line 236 from:

$events = get_upcoming_events($options['userid']);

to:

$events = get_upcoming_events_for_user($options['userid']);

The widgets page now loads without error and the events display as expected.

Hope this helps someone, but also as a note to Yoost to investigate further when he has the time 🙂
