createPDF Errors on Test Server Requirements

Hi

Just purchased CreatePDF today and it's failing on Test Server Requirements.

The errors is are follows:-

• Passed! Run external program on serverTesting shell_exec() with command: pwd
  Result: /home/javeahom/public_html/cmsAdmin
  
  
• Failed! Test running PDF conversion program on serverTesting pdf binary with command: /home/javeahom/public_html/cmsAdmin/plugins/createPDF/wkhtmltopdf/wkhtmltopdf-amd64 -V
  Result: 0 bytes returned
  Error: No output returned from command! (Exit code: 135)
  
  
• Passed! Test downloading content from remote URLDownloading content from url with: getPage('http://www.google.com/');
  Result: HTTP status code 302
  
  
• Failed! Test converting a web page to a PDFCreated PDF with: HTML from: http://www.google.com/;
  Result: 0 byte PDF returned
  Error: No pdf output was returned!
  
  
• Visually review PDF outputVisually inspect the PDF below, correct any error message, then make sure the graphics and fonts display as expected:

I have read the forums and one suggestion was permissions.

I have set permissions on all files and folders to 0755 but still the same problem.

One thing to note though, this is installed on my development server and the URL for cmsAdmin is http://37.220.93.134/~javeahom/cmsAdmin/

Everything else is working OK, including Permalinks plug in so this may be a "red herring" but thought it worth mentioning anyway.

I look forward to hearing from you.

Kind regards

Andy
