I'm having trouble adding users to the confluence-administrators group. I saw another question about this but the solution that seemed to work for someone there did not work for me. When I try to add the user to the group I get the message ...
- Failed to modify group memberships. Check your server logs for more information.
Can anyone tell me where this log is?
Confluence is installed locally on a Ubuntu server.
I'm working in Confluence 5.7.4 although this problem has existed for quite a while. It did not exist when I installed the system 3 years ago. I do not know what version it started with.
