Error: Required property domain failed to validate

[pjackson]

I've imported both contacts and companies before but i cannot get it to work today. Every domain is reported as invalid:

Error: Required property domain failed to validate - " www.bt.com" is an invalid domain

As an example.

I even tried taking off the www. prefix but still no joy.

Hey @pjackson, 

Can you check to see if there are any spaces before the text in the column with the domains? If you try to upload "_bt.com" as opposed to "bt.com" (where the _ is a space), it won't validate the domain. 

Let me know how you get on with that. 

Thank you,

Jenny
