Hi,

Please following these steps:

a. Ask your hosting to turn on PHP's display_errors, add the following command to the beginning of your export.php:

    error_reporting(E_ALL);

b. Post your export.php code.

c. Let us know where you unzip phantomjs file to and whether the file has executable permission. Assuming you could connect via ssh to your server, you could make it executable with this command:

    sudo chmod +x your/path/to/phantomjs
