Error 500 after last Plugin Update (original) (raw)

• Hello
  I just updated the advanced ads plugin to the latest version. Unfortunately now my blog and also admin backpanel gives me an Error 500. When i disable the advanced ads plugin through ftp access the page loads normally.
  Server Error logs shows:
  I: server “/var/run/hcgi/36137” stderr: PHP Fatal error: Uncaught Error: Call to a member function get() on null in ***/wp-includes/query.php:28
  ****
  FastCGI: server “/var/run/hcgi/36137” stderr: #8 ***/wp-content/plugins/advanced-ads/classes/ad-model. in ***/wp-includes/query.php on line 28
