I have a website where I worked with the Newsletter plugin (version 3.6.3). I am now customising an new theme for the website, I uploaded and customised the Newsletter plugin and want to have the subscribers imported. I get errors while doing this via the export and import the CSV files between the two versions of the plugin: I am exporting from version 3.6.3 and importing to version 4.2.0.
I am having additional fields in the subscription form (additional from the standard form), but the fields are the same for both versions.
The error message I am getting is:
Import completed but with errors.
Import completed: 1252 errors, 0 added, 0 updated, 0 skipped.
[INVALID EMAIL] email first name last name gender Profile 1 Profile 2
Same error for all 1252 subscribers.
Thanks a lot in advance!
