  cannot create course 16 3b Cannot modify header information

  Hello
  I wish you a happy 2008!
  We are trying to work with 1.6.3b. Installation went ok (no warnings, no errors) but we are unable to create a new course.
  More specifically when facing http://myip/ATutor/users/create_course.php, the form is interrupted at the point of custom icon selection. The Apache error.log tells:
  
  [Wed Jan 02 12:04:08 2008] [error] [client 10.20.0.188] PHP Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/ATutor/include/classes/Savant2/Savant2.php:1358) in /var/www/html/ATutor/include/header.inc.php on line 17, referer: http://10.20.0.23/ATutor/users/browse.php
  [Wed Jan 02 12:04:08 2008] [error] [client 10.20.0.188] PHP Fatal error: Cannot redeclare get_num_new_messages() (previously declared in /var/www/html/ATutor/include/lib/menu_pages.php:258) in /var/www/html/ATutor/include/lib/menu_pages.php on line 270, referer: http://10.20.0.23/ATutor/users/browse.php
  
  
  Can you please help us?
  
  My Enviroment is:
  operating system - CentOS 5.1
  version of ATutor - 1.6-beta3
  versions of php - php-5.1.6-15.el5
  version of mysq l - mysql-5.0.22-2.2.el5_1.1
  webserver & version - httpd-2.2.3-11.el5.centos

  changes to default settings - atutor content directory is /opt/ATutor/content
  web browser being used - firefox 2.0

  Try creating a course without the icon. You can add it later through the course properties screen.
  
  thx for pointing out the problem.

  Rather clumsy way to solve this problem

  Dear Greg,
  I managed to bypass the problem by commenting out most code of include/html/course_icon.inc.php:
  
  <?php
  // check if GD is installed
  /*
  if (!extension_loaded('gd')) {
  require(AT_INCLUDE_PATH.'header.inc.php');
  $msg->printInfos('FEATURE_NOT_AVAILABLE');
  require(AT_INCLUDE_PATH.'footer.inc.php');
  exit;
  }
  
  $gd_info = gd_info();
  $supported_images = array();
  if ($gd_info['GIF Create Support']) {
  $supported_images[] = 'gif';
  }
  if ($gd_info['JPG Support']) {
  $supported_images[] = 'jpg';
  }
  if ($gd_info['PNG Support']) {
  $supported_images[] = 'png';
  }
  
  if (!$supported_images) {
  require(AT_INCLUDE_PATH.'header.inc.php');
  $msg->printInfos('FEATURE_NOT_AVAILABLE');
  require(AT_INCLUDE_PATH.'footer.inc.php');
  exit;
  }
  */
  ?>
  
  
  Then, I managed to get the page working ok and insert my courses.
  
  Hope this will get resolved in 1.6 (non-beta)
  
  Thank you
