Fatal error: please help!

Ever since my wordpress autoupdated I get the following message whenever I try go to http://www.nonsurgical.org/wp-admin or any other admin pages. Any suggestions why this is happening?

“Fatal error: Cannot use object of type WP_Error as array in /clientdata/apache-www/n/o/nonsurgical.org.au/www/wp-content/themes/enfold/framework/php/auto-updates/class-envato-protected-api.php on line 344”
