Hi, I hava updgrade Dokeos 1.8.x to Chamilo 1.8.7.1 and when I clic on a link (i.e. in document section) I have this message:

Not Found

The requested URL /dokeos/main/document/download.php was not found on this server.

If I clic on download icon I can dowload file but if I clic on the file I have the error. This error appears for pdf files, html file, ... Other navigation work fine (I can create courses, edit courses, add/remove file, ... )
