 * Hi,
 * Could you please upgrade MPDF library on the PDF & Print settings page if you
   didn’t do it yet? Please follow the next instructions in order to upgrade MPDF
   library for the PDF&Print plugin:
 * 1) Go to the PDF & Print settings page;
    2) Open the “Misc” tab; 3) Click the“
   Upgrade” button; 4) Test the PDF doc creation and let us know about the result.

 * I’ve tried the upgrade on the setting page, but after 10 minutes is hasn’t completed.
   How long should it take?

 * Going back to the ‘Misc’ tab, upgrade isn’t there. Just ‘pro options’, ‘track
   usage’ and ‘default settings’. Am I looking in the wrong place.
