Editing the lib.php file is one possible work around for resolving an issue with a Moodle installation completed through Fantastico in cPanel. Once the installation is complete and an administrator logs into Moodle, a blank white screen<\/a> appears instead of the expected administration error. This error, caused by a PHP version mismatch can be resolved through either editing the lib.php file or manually installing an older version of Moodle that doesn’t require PHP 5.3.<\/p>\n

Before making changes, making a full backup<\/a> is highly recommended.<\/p>\n

Fortunately, editing the lib.php file can easily be done through the cPanel File Manager<\/a> and we’ll walk you through it:<\/p>\n

    \n
  1. Log into cPanel<\/a>.<\/li>\n
  2. Click on “File Manager” and navigate to the question\/engine subfolder inside your Moodle installation (i.e. public_html\/question\/engine, \/public_html\/moodle\/question\/engine or something similar depending on where you installed Moodle).<\/li>\n
  3. Select the lib.php, right click it and choose “Code Editor” to open the file for editing.<\/li>\n
  4. Find the following lines of code:<\/li>\n

    public static function get_behaviour_required_behaviours($behaviour) {
    \n$class = ‘qbehaviour_’ . $behaviour;
    \nreturn $class::get_required_behaviours();
    \n}<\/p>\n

  5. Replace:<\/li>\n

    return $class::get_required_behaviours();<\/p>\n

    With:<\/p>\n

    eval(‘$ret = ‘ . $class . ‘::get_required_behaviours();’);
    \nreturn $ret;<\/p>\n

  6. The function should now look like this:<\/li>\n

    public static function get_behaviour_required_behaviours($behaviour) {
    \n$class = ‘qbehaviour_’ . $behaviour;
    \neval(‘$ret = ‘ . $class . ‘::get_required_behaviours();’);
    \nreturn $ret;
    \n}<\/p>\n

  7. Click the Save Changes<\/strong> button in the upper right of the window.<\/li>\n<\/ol>\n

    Now, when we go back to our site where Moodle is installed we can log in and see the Moodle administration area.<\/p>\n","protected":false},"excerpt":{"rendered":"
