title: Blank Output PDF using FPDF library - codeigniter
body: <p>I'm going to generate a PDF report using FPDF library, but the output is blank.  There is no error displayed, how can I fix this problem? </p>
  
  <p>Anyway, I tried this code in LOCALHOST and it works perfectly, but when I upload it to the cloud, there's no output to be displayed.. I tried to make the function output like this..</p>
  
  <pre><code>$this-&gt;fpdf-&gt;OUTPUT('try.pdf','I'); but nothing happens..
  </code></pre>
  
  <p>NOTE: In my output, C:/backup/employee_..php, the output is in the folder, there's no error and it works fine.. but when I upload this one, there no output to be display</p>
  
  <p>This is my CONTROLLER:</p>
