The most common causes are to do with the contents of the CSV uploaded file. Please check for the following:
There are atleast columns for organisation name and jurisdiction
The jurisdiction column contains country names or valid jurisdiction codes (see jurisdictions list)
Columns were correctly mapped during the import setup
There are no formatting issues (check file by opening in Microsoft Excel or similar program)
If you find any issues, try the upload again. If you see repeat errors, please get in touch and a member of the team will be able to assist.
