Thank you for solving the problem we got exporting the users’s CSV from a 4.1.18 version of WP.
We did it to many HW (PC, Samsung smartphone, . . . ) and SW (Windows, Linux, Android, . . . )
Next week we will try it with an older 3.9.2 version of WP.
Regards
The size of the downloaded CSV file is VERY SMALL. Only 8 kb for 212 “users” and 12 parameters by user.
Thus with a comma (‘) and open and closing double quote (“) by parameter, it means around 212 x 12 x 3 = 7632 characters ot bytes.
It means also that the file don’t contain useful user’s informations.
For me the problem is not at the spreadsheet application level, but at the generation level in the parameters of WordPress or of that plugin.
But where ?
