Just last week we discovered that we could no longer add or manage users. That’s when we realized that the Site Administration area was empty of menus, except for Front Page. As administrator, I cannot access a course, receiving the message “you cannot enroll yourself in this course”, nor see any of our users. Our host restored an earlier backup, but with no improvement. Teachers and students are still able to access all features of Moodle applicable to them.
I no longer know which version we are using, since without admin privilege functioning, I can’t access it. But it would be the version we started using about two years ago and have not upgraded.
I would appreciate any suggestions or advice.
