  <p>Can any one help me to fix it?
  Thanks</p>

  <p>Ok, I fixed it. For people get the same problem: note that the error "Fatal error: Maximum execution time of 30 seconds exceeded"</p>
  
  <p>The solution is:<br />
  1. go to php.ini file and file the following code snippet </p>
  
  <pre><code>;;;;;;;;;;;;;;;;;;;
  ; Resource Limits ;
  ;;;;;;;;;;;;;;;;;;;
  
  ; Maximum execution time of each script, in seconds
  ; http://php.net/max-execution-time
  ; Note: This directive is hardcoded to 0 for the CLI SAPI
  max_execution_time = 30
  </code></pre>
  
  <p>2.change <code>max_execution_time</code> into 100 or more. Because there are maybe some scripts need more than 30 seconds to execute.</p>
  
  <p>Good luck</p>
