I have installed the contact layout editor extension on Drupal 7 and could not see editor when selecting contact summary layouts. I upgraded CiviCRM to version 5.19.2, enabled Shoreditch still nothing. All extensions are shown up to date. All I see when selecting the editor is this error messsage
Notice: Undefined index: target_contact_name in getContactActivitySelector() (line 2608 of /home/webdevelopmentsc/public_html/sites/all/modules/civicrm/CRM/Activity/BAO/Activity.php). =>
Any help or assistance would be appreciated.
