title: How to fix PHP Deprecated Automatically populating $HTTP_RAW_POST_DATA is deprecated issue?
body: <p>hello i'm getting this error in my error log:</p>
  
  <p>"<strong><em>PHP Deprecated:  Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0</em></strong>"</p>
  
  <p>My wordpress version is 4.8.1 and the php version is 5.6.30.</p>
  
  <p>I tried fixing the issue by creating a php ini file and setting always_populate_raw_post_data value to -1. But i still get the error. </p>
  
  <p><strong>If it cannot be fixed</strong>, how can i prevent it prints on the error log?</p>
  
  <p>I'm using a shared hosting. </p>
