I tested the grid format on my shared server and it worked fine. Installed it on my server at school, it tried to create a course using Grid format and bang
Notice: Undefined property: stdClass::$students in /afs/csl.tjhsst.edu/web/www/studentlife/activ/nhs/course/format/grid/format.php on line 21
Moodle 2.1.3(build 20111128) on both and used the same download for Grid Format.
So i decided to delete the new course. BUT, it doesn't delete from the front page and it still in the new/edit course menu.
If I enter the course I get the same error message, plus "insert_record() isn't available anymore" so it looks like its half way deleted.
I really like the way grid works, but I'm baffled as to why its only broke on one installation.
I'm also baffled about how to really kill the botched up course.
Thanks in advance
