HAP 9 setup error - object reference not set to an instance of an object
I am trying to set up Home access plus but am running into a problem completing the setup pages. It's all setup in IIS and file permissions. I have got the three green ticks on the front page.
When i move to the Active Directory User List OU's for teaching staff etc i get the following error message "object reference not set to an instance of an object" when i try save them. The pop up appears with my AD tree fine and i was able to select the student group fine. I also get the same error when i try to add a lesson on the room bookings tab.
Any ideas what could be causing this?
