title: MySql Error: 1364 Field 'display_name' doesn't have default value
body: <p>I have just switched from a MAMP installation to a native Apache, MySql and PHP installation. I have got everything working, but I have started using my web app in the new environment and suddenly any INSERT commands are resulting in the following error:</p>
  
  <blockquote>
    <p>SQLSTATE[HY000]: General error: 1364 Field 'display_name' doesn't have a default value</p>
  </blockquote>
  
  <p>It seems the I am unable to leave a field blank now where I was able to before. I am using MySql version 5.6.13</p>
  
  <p>Is there a way to change this setting in MySql?</p>
