I prepared a CSV for upload. I'll have to make multiple passes on the upload because I have single entry items and multiple entry data in the spreadsheet. I have created all of my custom fields. I can do a standard contact import with the unsupervised rule.
I see that I need an ID number for the multi-record import. I installed the CSV Import Helper to prepare for the multi-record import. When I select the CSV (I'm using the ; for my field delimiter) I get the DB error: unknown error from CiviCRM.
I'm on WordPress with CiviCRM 5.20.1
The only error I see in the Civi error log is :
[26-Feb-2020 16:20:05 UTC] PHP Notice: Undefined index: SERVER_NAME in /home/websiteweb/public_html/wp-content/plugins/LayerSlider/classes/class.km.autoupdate.v3.php on line 75
[26-Feb-2020 16:20:06 UTC] PHP Warning: session_start(): Cannot start session when headers already sent in /home/websiteweb/public_html/wp-content/plugins/civicrm/civicrm.php on line 364
My end goal is to merge the contact IDs into the data set so I can proceed. Any advice is welcome.
