I'm getting the fun "unable to create invitation" message. I checked my permissions and they are all checked. I've never had an issue with this before. Originally this was happening with JSS 10.3.1 and Casper imaging 9.100. I upgraded the netboot to use jamf imaging 10.3.1 (or whatever the latest is) and I'm still having the issue. I've looked at 4-5 other posts for solutions but none of them have worked for me.
EDIT: After looking at This I guess I'm not the only one. How am I supposed to image older machines? Get your act together. A lot of people pay you a lot of money and lately, all I see is one thing being fixed and 5 more breaking.
