Trying to send email messages, they get stuck at 40/129 and then later i get a message that says "Campaign has been paused due to sending errors: could not execute: /usr/sbin/sendmail.
Also sometimes when I move to a different page of the wordpress admin I get a fatal error "Fatal error: Cannot use object of type WP_Error as array in /home/content/05/11097405/html/wp-content/themes/alterna/envato-wordpress-toolkit-library/class-envato-protected-api.php on line 344"
Any ideas or insight would be great need the email system to send out order forms.
