I have the book 16 mod installed but am having a few issues when I try to delete a course in that I recieve the following error.
Fatal error: Call to undefined function: book_16_delete_instance() in /var/www/vhosts/unitsonline.school.nz/httpdocs/classroom/lib/moodlelib.php on line 2736
The line 2736 is: notify('Function '. $moddelete() .'doesn\'t exist!');
