I'm very used to setting up permissions for individual private nodes and I've never had any issue. I've just created a new node, set it to private and given permissions to the relevant usergroup. I did that again today, and a user then told me they couldn't access it properly. I double checked I'd also given full permissions on that node for my own admin usergroup and tried to access it myself. I can view the forum, but I have no permissions to post. Nothing is set to revoke or never on any other usergroup, I just used the private node feature as always. Any ideas?
