I recently purchased this course and none of the pdf files are downloadable. The error msg:
Warning: require(/var/www/shell.php): failed to open stream: No such file or directory in /var/www/p.php on line 49 Fatal error: require(): Failed opening required '/var/www/shell.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/p.php on line 49
