It looks like this (there are many more groups, but they were clearly created by us and didn’t have any resemblance with the system groups, so I didn’t include them below):
=> [["everyone", 0],
["moderators", 2],
["admins", 1],
["trust_level_0", 10]
["trust_level_1", 11],
["trust_level_2", 12],
["trust_level_3", 13],
["trust_level_4", 14],
["Staff", 42]]
I notice that there is no group staff, only Staff - if staff always has id 3 then I guess this indicates that somebody removed it and created a new group (id 42).
Is it enough to create staff again or how can I solve this?
