When attempting to send an email to event participants (via participant listing > action > send email), I receive the following error:
Cannot read unrecognized property CRM_Core_Config::$civiVersion.
Upon trying to send to them as a group via CiviMail, I also get the same error in my process_mailing log
Any advice on how to resolve this would be appreciated!
Running CiviCRM 4.7alpha5 on Wordpress 4.3.1 with Mandrill and Clickatell extensions installed
