Eudardo, Klaus, and all who've posted on this Solution module.
It was working well (version 2004121505) for me in Moodle v.1.4.3 as I used it to include copyrighted materials (permission granted from publisher) in my nonf2f course, however, our sysadmin moved everything to a new server with a concurrent upgrade to v.1.5.1 and now I get
"A required parameter (sesskey) was missing"
I really need this to stay compliant with my use permission (informal licence).
Suggestions? I'm not the systems administrator (who doesn't speak English) so please make this straightforward for me. Thanks.
