title: Database connection settings with DB_DEBUG set as FALSE
body: <p>I'm trying to connect to my database but i get the following message:</p>
  
  <p>Unable to connect to your database server using the provided settings.</p>
  
  <p>Filename: core/Loader.php</p>
  
  <p>Line Number: 346</p>
  
  <p>So after reading a lot, I found that setting $db['default']['db_debug'] to FALSE in database connection solves it. I did that and the error message disappeared; the website's first page loaded too but it had no database calls. From then on I started getting errors during my database calls, the query were possibly not returning query objectts.</p>
  
  <p>So I want to know does DB_DEBUG actually solves the problem connection or it simply masks the problem that the DB connection errors do not show?  </p>
