title: database connected but not responding as expected when queried
body: <p>I have a database online that has been running fine with my application until yesterday when it started to behave strangely.</p>
  
  <p>For example when a user does an operation that inserts data into my database(db), I was able to see the changes when I logged in as the admin.</p>
  
  <p>Now a client inserts data into my db but when I want to view that from the application, nothing is displayed but insertion is actually made on db.</p>
  
  <p>I thought my database crashed but when I check my db it shows all tables are OK.</p>
  
  <p>To debug the app I downloaded the app and the same db to work on it locally, but the same app and db works smoothly and as expected locally.</p>
  
  <p>The app is developed <strong>Codeigniter 2.1.4</strong> framework and I used <strong>doctrine 1.2.1</strong> to create db tables and most queries are done using this doctrine helper. </p>
  
  <p>My online server runs on <strong>PHP version 5.4</strong> and <strong>MYSQL version 5.5</strong> while the local server has <strong>PHP version 5.5</strong> and <strong>MYSQL version 5.6</strong>. </p>
  
  <p>What really might be the problem here?</p>
