File Import no errors, but no import either?

Hi, I am importing a text doc of users – the same way as always done (there are 5000 members successfully imported last time I used this function).

I am not getting any errors, it recognises the column declaration, but still doesn’t import the users (I searched users to check). See below result:

Column declaration found on line 1, the following column order is assumed: user_email, first_name, last_name, roles

0 valid entries have been read.

0 entries have been skipped.

0 users have been imported.

0 users have been updated.

Why is this? Please explain – without the import function, we would have to do manually and would take too much time.

Thanks, please let me know a resolve when you can.

Regards
Greg
