Just so you know, this was the problem: the first column, which is reserved for username, was also the first name of each user. Since a WP user needs to have a unique username, the import skipped through every repeated name, importing about half of them.

I hope this helps other people in case the same thing happens to them.

No errors. In fact the message I always get is that the import was successful but then not even half of the users are actually created.

Nope. The problem also happens importing the same file in other WP websites. There seems to be something wrong with the CSV file. Maybe something about special characters? Changing it from unicode utf-8 to ascii gives me a few more users but still not all of them. It’s very strange.

Thanks, Javier. I did try splitting the file in 3 parts. Tried it both on my local server and production host. Still same result: 203 users are created. I checked any similarities between failed records but didn’t find any, so I can’t see how some users are created and others are not. Any idea?
