OSCALENDAR VERSION 7

Hello, I have bought version 7 of oscalendar now in December 2018, I have installed the component with osproperty 2.4 and I can configure it, but when wanting to put the disposition it sends me the following error:
Fatal error: Call to undefined method OSappscheduleProperty :: editConfig () in /home/s21fdc39/public_html/spainhome.net/administrator/components/com_oscalendar/classes/property.php on line 30.
Also on the home page only presents the title.
My question is I have to buy the latest version of osproperty so that oscalendar works for me, can you help me with this error? Thanks a hug.

Hi Bryan,
I think the issue has cause from your OS Property version. You should upgrade OS Property to latest version to make OS Calendar to work properly. By the way, you also need to upgrade Joomla to latest version to make sure OS Property and OS Calendar to work well too.
Thanks
