I've successfully installed Adapt authoring tool and have mongod service active/running and node server up and a running, listening on port 5000. However, when I try to save a new a course, it gets stuck on 'saving' and won't proceed any further. Then I'm unable to do anything else; I'm just stuck on the one screen (unable to even log out of the authoring tool). Please help with some suggestions. I've attached what this issue looks like...
