Hi,
Thanks great mod for the calendar but I am getting a few deprecated errors on the backend and front end

Backend and Frontend
Notice: /home/kilve/public_html/beta/wp-content/plugins/the-events-calendar-filterbar/src/deprecated/TribeEventsFilter.php is deprecated since version 3.10! Use Tribe__Events__Filterbar__Filter instead. in /home/kilve/public_html/beta/wp-includes/functions.php on line 3510

Notice: Undefined variable: args in /home/kilve/public_html/beta/wp-content/themes/KilveCourt/functions.php on line 584

Frontend
Notice: /home/kilve/public_html/beta/wp-content/plugins/the-events-calendar/src/deprecated/TribeEvents.php is deprecated since version 3.10! Use Tribe__Events__Main instead. in /home/kilve/public_html/beta/wp-includes/functions.php on line 3510

Any idea how to fix this?

I am using the following versions:
The Events Calendar = 3.12.1
The Events Calendar PRO = 3.12
The Events Calendar: Filter Bar = 3.12

Thanks
Nick
