Debugging

PHP Errors

Add the following to the second line from the top (right below the <?php) of LocalSettings.php:

error_reporting( -1 );
ini_set( 'display_errors', 1 );
$wgDebugToolbar = true;
$wgShowExceptionDetails = true;
$wgDevelopmentWarnings = true;
$wgShowDebug = true;

This will configure MediaWiki to show the errors in page.

Also add in index.php:

error_reporting( -1 );
ini_set( 'display_startup_errors', 1 );
ini_set( 'display_errors', 1 );

SQL Errors

Add in LocalSettings.php:

$wgShowSQLErrors = true;
$wgDebugDumpSql  = true;
