When doing an import for existing contact that I want to update, after selecting Fill (For Duplicate Contacts), I get a Warning, a Notice but no import :
Warning: array_pop() expects parameter 1 to be array, null given in CRM_Contact_Import_Parser_Contact->import() (line 706 of /var/data/sites/sitename/public_html/sites/all/modules/civicrm/CRM/Contact/Import/Parser/Contact.php). Notice: Undefined offset: 1 in CRM_Contact_Import_ImportJob->_addImportedContactsToNewGroup() (line 393 of /var/data/sites/sitename/public_html/sites/all/modules/civicrm/CRM/Contact/Import/ImportJob.php).
There is a Warning and a Notice for each contact submitted.
The Dedupe Rule is selected to Email The version of CiviCRM is 4.7.22
I have a feeling that something is corrupted in the database.
Thanks for your help.
