Hi guys, I'm switch to display a Calendar view or Graph view or Gantt view in my base; but i have error like this:

Uncaught TypeError: object is not a function
http://178.000.000.138:8069/web/webclient/js?db=mybase:3281

I try to upgrade installed modules web_calendar, base_calendar, but that does not help. 

I have other databases installed on the same server , which worked properly .

Do you have the opinion that for the type of error and in what direction to explore ?
