This is weird, the error is generated when a post type `Bibliography` is created, if it fails creating a post of that kind with the name: `BIBSDB`, it will output the error.
Can you enable debugging in Courseware?
Edit the line #15, and change:
`
define( ‘BPSP_DEBUG’, true ); // This will allow you to see post types in wp-admin
`
See here:

Btw, what’s the WordPress version you use?
You need at least 3.0, you know that, right?!
Yep, 3.0. I’ll try editing later, I’ve not got time at the moment.
Thanks 
I am also having trouble with the bibliography. I have the newest version of wordpress, buddypress and courseware on a clean install with the default buddypress theme … I can add web addresses to the bibliography using the quick add. They appear in the list when I return to bibliography management but when I am in the course overview, it shows the bibliography as having no items in it. What have I done wrong? What do I need to do to display the bibliography to students in a course group? Thanks. I hope you can help.
@sellarsc you need to quick add bibliographies directly on the lecture/assignment page. Also please open separate threads for different questions.
Thanks.
