I have the same problem and not show anything in the log, how do you could fix it?, I use 1.4.6, the format of my csv is:
Jon Doe;address client;;city of client;state of client;zip client code;country client;phone client;;mobile phone client;email client;;vat number of client;;1
I see a similar issue on post:
But do not tell how could fix it, I retry the import replacing “;” by “,” and still not work.
Thank you, regards.
