 * Hi there!
 * First off, thank you for this plugin. It works perfectly but for one issue. I
   would like to send my invoices as soon as someone places an order, not afterwards.
   Unfortunately, if I have the ‘customer processing order’ setting selected, the
   following error shows up when placing an order:
 * `Fatal error: Cannot redeclare class mPDF in /wp-content/plugins/woocommerce-
   pdf-invoices/mpdf/mpdf.php on line 65`
 * The order goes through though, it does register and an admin email is send, just
   not to the client. Any way to fix this? Thanks!

 * Found a fix for this issue: on line 84 you can find `include(BEWPI_PLUGIN_DIR.'/
   mpdf/mpdf.php');`. Replace it with:
 *     ```
       if(!class_exists('MPDF')){
        include(BEWPI_PLUGIN_DIR . '/mpdf/mpdf.php');
        }
       ```
   
 * Works for me now, without any errors. Sends off all emails perfectly!

 * Hi there,
 * I’m unable to find include(BEWPI_PLUGIN_DIR . ‘/mpdf/mpdf.php’);
 * Is there something I’m missing? It should be just before the EXTERNAL (PUBLIC)
   VARIABLES area, correct?
