 * I have an WordPress installation that integrates Beaver Builder, Ultimate Addons
   for Beaver Builder, and WPML for multilingual. The creation of a PDF does not
   work on any page. Printing, on the other hand, goes. The following errors are
   emitted:
 * Warning: Illegal string offset ‘ID’ in /var/www/web623/html/hindelang/wp-content/
   plugins/pdf-print/mpdf/classes/cssmgr.php on line 1136

    mPDF error: Some data has already been output to browser,
   can’t send PDF file
 * Unfortunately, I have no plan why this could be! Actually I was planning to buy
   the Pro version, but the plugin should work already!
 * If I set Dispaly_Errors to off it works. But it can not be the sense that the
   errors are present! Will there be an update soon?
 * Greetings
    Sascha

 * Hi,
 * Thank you for contacting us.
 * To generate PDF documents our plugin uses the mPDF v6 library that has compatibility
   issues with the PHP 7. This issue has been fixed in the mPDF library v7 and we
   will implement a new version in the future plugin updates.
    Meanwhile, disabling
   the error displaying is the easiest way to avoid the issue.
 * We cannot provide any terms for the update because we have many other plugins
   scheduled to be updated first.
