Comment 1 for bug 1172660

I get permission errors when viewing personal details or group contents... Even when I took some fixes from a newer version...

But ok, this is a new error. I can reproduce it if I go to http://localhost:7080/groups , but am not sure how a teacher could have got there. Could you describe what were you doing in a little more detail? Look at a person, expand the Groups part at the bottom, click on one of the groups, e.g. Teachers, to see it, and click Done link there? I get a "You are not allowed to access" page, but anyway the Groups list is not where I would expect to return.

There is one thing you can do to avoid this error, without us fixing navigation and permissions for teachers. As manager, go to Server tab, click Security in the sidebar, then click Edit icon next to Access Rights heading. Find "List of groups" and select " The list of groups in the system is visible to the general public." and Submit. Then the teacher will be redirected to the list of Groups, if I guessed your actions right. Probably not what you expect, but not an exception either.

Or you can use the browser's back button to go where you were before :)
