Hi Alec, thanks for answering.
I knew about the demo site, but it looked like a real conference, hence, I didn't dare changing anything in it! Anyway, I have created an author and a director/track director, submitted/accepted a paper/presentation, and my first result is that if not logged, or logged as an author only, I can not access the documents, while if logged with higher privileges, I can. Conference Site Management/2.4 Access to Conference Presentations is set at "Provide open access to all visitors to the website".
If you go to the site right now and browse by title, you will see (or not) the presentation, depending of your login type. Same if you follow the "Presentations" link on the right panel: http://pkp.sfu.ca/ocs/demo/index.php/sp ... sentations
(you will either see the list or see "You do not yet have access to this conference's presentations")
So why is it access right seems to be enforced while it seems it is set to "open access"?
Thanks for helping me understanding this
