Thanks for the help. I deleted the codes I added in config.php and uncommented section 7 of my config-dist.php like this
//=========================================================================
// 7. SETTINGS FOR DEVELOPMENT SERVERS - not intended for production use!!!
//=========================================================================
//
// Force a debugging mode regardless the settings in the site administration
@error_reporting(E_ALL | E_STRICT); // NOT FOR PRODUCTION SERVERS!
@ini_set('display_errors', '1'); // NOT FOR PRODUCTION SERVERS!
$CFG->debug = (E_ALL | E_STRICT); // === DEBUG_DEVELOPER - NOT FOR PRODUCTION SERVERS!
$CFG->debugdisplay = 1; // NOT FOR PRODUCTION SERVERS!
//
// You can specify a comma separated list of user ids that that always see
// debug messages, this overrides the debug flag in $CFG->debug and $CFG->debugdisplay
// for these users only.
$CFG->debugusers = '2';
//
// Prevent theme caching
$CFG->themedesignermode = true; // NOT FOR PRODUCTION SERVERS!
//
// Prevent JS caching
$CFG->cachejs = false; // NOT FOR PRODUCTION SERVERS!
//
// Restrict which YUI logging statements are shown in the browser console.
// For details see the upstream documentation:
// http://yuilibrary.com/yui/docs/api/classes/config.html#property_logInclude
// http://yuilibrary.com/yui/docs/api/classes/config.html#property_logExclude
$CFG->yuiloginclude = array(
'moodle-core-dock-loader' => true,
'moodle-course-categoryexpander' => true,
);
$CFG->yuilogexclude = array(
'moodle-core-dock' => true,
'moodle-core-notification' => true,
);
//
// Set the minimum log level for YUI logging statements.
// For details see the upstream documentation:
// http://yuilibrary.com/yui/docs/api/classes/config.html#property_logLevel
$CFG->yuiloglevel = 'debug';
//
// Prevent core_string_manager application caching
$CFG->langstringcache = false; // NOT FOR PRODUCTION SERVERS!
//
// When working with production data on test servers, no emails or other messages
// should ever be send to real users
$CFG->noemailever = true; // NOT FOR PRODUCTION SERVERS!
//
// Divert all outgoing emails to this address to test and debug emailing features
$CFG->divertallemailsto = 'root@localhost.local'; // NOT FOR PRODUCTION SERVERS!
//
// Uncomment if you want to allow empty comments when modifying install.xml files.
$CFG->xmldbdisablecommentchecking = true; // NOT FOR PRODUCTION SERVERS!
//
// Since 2.0 sql queries are not shown during upgrade by default.
// Please note that this setting may produce very long upgrade page on large sites.
$CFG->upgradeshowsql = true; // NOT FOR PRODUCTION SERVERS!
//
// Add SQL queries to the output of cron, just before their execution
$CFG->showcronsql = true;
//
// Force developer level debug and add debug info to the output of cron
$CFG->showcrondebugging = true;
I still see only a Blank page. What am I doing wrong?
