WSOD or white screen of death and error reporting

Database API, several ways to retrieve data from query 



$uid = 1;
$result = db_query('SELECT n.nid, n.title, n.created
FROM {node} n WHERE n.uid = :uid', array(':uid' => $uid));

Fetch next row as a stdClass object.
$record = $result->fetchObject(); 

Fetch next row as an associative array.
$record = $result->fetchAssoc();

Module paths in DB

Working with multi sites and modules located in sites/all and sites/some_site your module paths could get in problems. So for a fix check you just need to replace paths in your DB like

Drupal missing modules and white screen of death

WSOD (white screen of death) can happen in drupal for different reasons. One is that you could be missing some files, probably modules. Maybe you moved something wrong when migrating, or you have wrong git branch or just delete module(s).
