Forum .LRN Q&A: Re: Getting dotlrn installed and configured on a working 5.912 OACS
just to clear the room from -not always obvious- problems: you installed dotlrn, but have you mounted the application somewhere? Seems like /dotlrn path in your server doesn't point anywhere.
Another thing that could have gone overlooked is some error appearing during package installation. Did all go smooth?
If these were not problems, I'd suggest you to try re-installing following previous indications: sometimes new changes can be interdependent with other packages and you really need to have an updated instance for things to work out.
All the best
