No "add calendar/item" button or link

The free version supports one calendar. There is also pro version (commercial) that supports unlimited calendars, if you already have the pro version then be sure to install it to enable those options. You can check the details about the plugin versions at this page:

Thank you.

Thanks for the answer… I didn’t read anywhere that the free version was limited. So, i understand now why i can’t add more calendars…

Thanks anyway
