Unable to use noticeboard

I have recently installed your school management plugin on my wordpress
webpage. However, I am running into some issues when trying to post
something to the noticeboard.

Issue 1: Notices posted are not being shown on student dashboard.

Issue 2 : Notices can’t be issued to specific students of a class. I
get an error message – unknown coloumn ‘student_school_id’ in ‘where clause’

Could you help?
