After following instructions for installation, which went apparently correctly, when I browse to the web page with the php include at top to user.php, I get "cannot find user.php" no matter how I have used the string provided or altered it to try and work correctly.
Then when entering manager.php I get:Warning: file(****/users.php) [function.file]: failed to open stream: No such file or directory in /home/*****/public_html/******/*****/*****/flatfile.inc.php on line 81, line 84, line 188, line 121 and none of the new users are being added.
